DeepSeek CEO explains how he has transformed the chip shortage into his strategic alibi

by

One of the many battles that China and the United States are fighting is technological, specifically one related to artificial intelligence. US business spending on AI It’s astronomicalbut in China the ambition is no less and the Government wants it to be one of the pillars for the country to be the first world power in the short term. One of the conversations surrounding Chinese AI compared to American AI has to do with efficiency. Very capable models, higher in some cases to the Americans, but with a much lower price and, above all, trained in record time. There are controversies about it, such as theft accusations by giants like Anthropic and OpenAI, but the reality is that if you don’t want to use the AI ​​of an American company, they are there alternatives like DeepSeekKimi or those from Zhipu AI. But, speaking of Deepseek, the company’s CEO is clear that there is a Huge difference between Chinese AI Big Tech and American counterparts: computing capacity. He gives a fact to illustrate it: four Huawei chips are equivalent to one from Nvidia, and that opens the door for the US to have even more arguments to continue putting pressure on the Chinese technology industry. The bottleneck is power, nothing more Liang Wenfeng He is the CEO of DeepSeek and, like so many in his position in recent weeks, he has had the presentation before investors. These types of events are very interesting because they allow us to learn more about both the companies and their plans, and in this case it has been revealing to listen to the head of one of the most relevant AI companies today. They are not official statements, since they are the leak of the almost four-hour meeting published by Tencent Tech, but among its many phrases, we can extract very interesting ideas. The first is what we mentioned: for the boss, the main gap is money and resources. “There is no gap in personnel, since it is basically the same group of people. Talent is not the bottleneck: resources are the biggest bottleneck,” says Liang. The CEO continued to point out evidence, stating that “more cards are always better” and that, at a reasonable price, they buy as many as they can because “converting money into Nvidia cards is definitely better than leaving that money in the bank.” And the Nvidia cards stand out for a fact that is also very interesting: how many Huawei cards are equivalent to one Nvidia card. “Our price offers a reasonable profit: we buy a batch of equipment and they pay for themselves in about ten months” – Liang Wenfeng Assures that the relationship is four to one, or what is the same: if they wanted to train a model with 800,000 million active parameters like the main American AI models, they would need 50,000 Nvidia GB300 cards or 200,000 Huawei 950 cards. That It doesn’t seem to leave Huawei in a very good place.which are those that the Chinese industry and the Government itself is trying to promotebut Liang affirms that Nvidia is digging its own grave in the Chinese market, that the CUDA ecosystem is eroding quickly and that Huawei supernode 950 It can completely replace Nvidia’s GB200 and GB300 in both performance and price. Although the 4:1 ratio between the chips seems alarming for the domestic company, Liang did not specify the workload or whether it measures raw performance, training performance or inference. The US looks closely One detail that Liang points out is that this computing power gap will end up closing as Huawei launches solutions and that, although he does not dare to guess when it will happen, it is something that will end up arriving. But of course, when the competition between the US and China is, in part, in that power of AI, the United States is not in the least interested in closing the gap. In recent months we have seen how pressure has continued to prevent Chinese companies from accessing Western hardware that is key to the development of the semiconductor industry. ASML Extreme Lithography Machines are an exampleand more recently the White House accused Chinese startup Moonshot AI from acquiring servers equipped with Nvidia chips that they should not be able to access. The case of Moonshot AI has been quite popular because a few days ago we told you about that amazing Kimi K3 model that, according to the Americans, would have been trained in Thailand with Nvidia GB300 chips to avoid United States export regulations. And they go further, arguing that Kimi K3 had ‘drunk‘the model Anthropic Fable. Deepseek Strategy Beyond politics, and returning to Liang, although right now it seems that China is not on par in terms of computing power, DeepSeek has a long-term strategy that has less to do with having the most powerful model currently. As we read in SCMPLiang commented that they are setting prices “to make only a reasonable profit, not to maximize revenue.” And that is the key that the company apparently pursues, since they are keeping prices low for users with the aim of their service being increasingly used in the hope of increasing the possibility of achieving artificial general intelligence. So while other companies prioritize immediate profits and capturing market share, Liang is focusing on “increasing the probability of achieving AGI“because it will be that AI that will have great commercial value. And that is what they do seek to exploit. In Xataka | While most oppose AI data centers, there is one group enthusiastic about them: merchandise thieves

Christopher Nolan explains why he filmed ‘The Odyssey’ in IMAX

by

Christopher Nolan has not chosen the 65mm IMAX format for ‘The Odyssey’ as a simple technical boast. In reality, for this director it is a narrative tool at the service of a mythological scale story. Homer’s poem tells of endless sea voyages, storms, monsters and a journey that tests the limits of human endurance. Nolan wanted the viewer feel that immensity in a physical waynot just intellectual. And the only way to achieve this, as the director himself explained, was to completely fill the visual field of the movie theater. This ambition explains why, unlike previous works such as ‘Batman: The Dark Knight’, ‘Interstellar’ or ‘Oppenheimer’where IMAX is reserved for certain sequences of great impact, in ‘The Odyssey’ this format is maintained throughout the entire footage. Nolan has thus broken his own habit of alternating formats according to the intensity of each scene. The Homeric epic demands that the feeling of grandeur never wane, not even in the most intimate passages of the plot. IMAX’s 1.43:1 aspect ratio, much more vertical than the usual widescreen image in commercial cinema, is the key to this decision. By filling the viewer’s peripheral vision, this format generates a sense of depth similar to 3D without the need for glasses, something Nolan considers essential to convey the magnitude of the landscapes and battles. The director has summed up his philosophy with a forceful phrase: it sought to offer the public “something new and exciting”, an experience that no other format could give with the same intensity. IMAX demands as much as it promises The heart of this creative ambition is an exceptional negative. The IMAX film format, technically known as 15/70, uses 15 perforations per frame compared to the usual four for 35mm, which increases the size of the negative tenfold. The result is a horizontal resolution that is around 18,000 theoretical pixels, compared to the 1,920 pixel width of a high definition home screen (which together with its 1,080 vertical lines makes up the Full HD standard), and a sharpness that Nolan considers unsurpassable even compared to productions shot directly in digital. Filming with this technology for an entire feature film has required developing new equipment. IMAX cameras are traditionally very noisy for filming dialoguesso the team created a silencer they call blimp (we can translate it as soundproof casing). The resulting camera, named ‘The Keighley’ after veteran IMAX executives Patricia and David Keighley, weighs about 300 pounds packed into its soundproof casing. Nolan maintains that the resulting image retains a quality superior to that of any digital production. In addition, the physical support adds another layer of demand. The celluloid tape had to be recharged every two and a half to three minutes, and a mirror system had to be installed so that the actors could see each other around this bulky device during filming. This celluloid also advances horizontally through the projector using a technique called rolling loopand a single 45-minute roll can weigh 140 kilos and exceed 4,600 meters in length. Nolan maintains that, even when this negative is scanned to digitize it and adapt it to rooms with laser projectors, the resulting image retains superior quality to that of any production born in digital. This conviction explains his insistence on defending celluloid against the advance of digital tools, a position that he has maintained consistently throughout his entire career. All this technical demand has a very high cost during the exhibition process: only about 40 theaters around the world can project IMAX in its full combination of 70 mm and giant screen, and finding trained personnel to handle these prints is increasingly difficult in an industry focused on digital for almost two decades. Spain, despite having several digital IMAX theaters and with projection in traditional 70 mm, it does not have any that combines both technologies, so the Spanish public will have to settle for digital versions that crop the image to a more panoramic aspect ratio, losing some of the visual information that Nolan captured at the top and bottom margins of the frame.

OnePlus closes in Europe and Realme closes in China. This is the logic that explains why it is not the other way around

by

Oppo has confirmed the movements that had been circulating for weeks about the future of OnePlus and Realmein an official announcement that sheds light on the future of each brand. The result is almost a mirror image between China and Europe: where one brand disappears, the other stays. And vice versa. What Oppo has confirmed. The distribution is like this: in ChinaRealme closes. OnePlus and Oppo remain. In Europe and SpainOnePlus closes. Realme and Oppo remain. Realme UIRealme’s customization layer, disappears and merges with ColorOSthe one from Oppo. Realme users will be able to voluntarily update to ColorOS, although there is still no confirmation of which model range this update will reach. The commitment to support and updates for devices already sold is maintained in both cases. The important nuance. It doesn’t matter how it was told in China: Realme does not disappear in Europe. It is an easy distinction to lose if international coverage simplifies the headline as “Oppo closes Realme” without further context, because the announcement is born in a Chinese key. In Spain and the rest of Europe, Realme continues to sell normally. The brand that is leaving our market is OnePlus, something that has already been talked about for months and that we counted a few days ago as something imminent. Between the lines. That Oppo closes different brands in each region depending on the strength they have there says a lot about its strategy. Realme has been the most aggressive brand in terms of price for years in markets such as Spain, France, Italy and the United Kingdom, with a commercial pull especially among the young public. In China, on the other hand, it is Oppo that dominates the terrain and Realme weighs less: It is the third after Huawei and Apple. Closing where it does not pay off and maintaining where it does work is a purely pragmatic and accounting balance decision. There is a second reading that the announcement has not yet clarified: it would not be strange for Oppo to distribute its brands by range in addition to geography, leaving Realme the entry and mid-range and reserving the high range for Oppo. The CEO suggests something like this, whose statement sent by the brand includes the phrase “OPPO’s European business remains stable, with strong momentum in the premium flagship segment.” On the other hand, the Realme that arrive in Spain in the coming months could be the successors of the low and mid-range OnePlus that the brand continues to manufacture in China with another logo. And now what. The announcement closes, on paper, the months-long mystery about the future of OnePlus in Europe. What remains to be seen is the fine print: what happens with Realme outside of Spain, up to what range the migration to ColorOS reaches and if the price distribution between Realme and Oppo confirms the hypothesis of the low range disguised as Chinese OnePlus.

the map of the 100 trials that explains everything

In order for ChatGPT, Gemini or Meta AI to respond well to the enormous number of questions that their users ask every day, years before the companies behind them made a decision: to obtain data at all costs and from wherever. Books, newspaper articles, song lyrics, illustrations, source code. Its premise was clear: it was Better to ask for forgiveness than to ask for permission. So today the courts are full of lawsuits, billions of dollars at stake and the AI ​​business model in the dock. For years, piracy was a matter of individuals downloading movies. Now it is the largest companies in the world that have done something similar, but on a large scale and with technology that structurally violates it. What the judges decide will mark how artificial intelligence is built from now on. Just as you prepare better for an exam if, in addition to taking the class book, you go to the library and read recommended books and expand with other readings associated with the topic you are reviewing, the different research teams behind the great AI models. it occurred to them that with huge datasets and from varied sources the result was better. The problem is that that tremendous volume of data does not fall from the sky: They took it from the web, from digital libraries and from LibGen or Z-Library repositories. The usual defense of companies like OpenAI is fair use and text and data mining exceptions, ensuring that they use unlicensed data legitimately. So the courts go case by case. Whether or not training AI models with protected content is fair use is the most important copyright question the courts have faced. Depending on the result, companies face a dark future: the payment of licenses retroactively, cleaning databases and of course, changing how they collect your data from now on. And they have lawsuits to bore: more than 100 active complaints in June 2026, according to the graph. It is important to note that this chart refers only to United States courts. Furthermore, in Europe it is a different story. The old continent has more restrictive regulations: it requires deleting data after use and allows creators to reserve their rights. The AI ​​Act requires publishing what data was used in training, something that companies have consistently avoided. The graphic in question is the work of David McCandless for Information is Beautiful and has been prepared using data from ChatGPTisEatingTheWorld.com, Wired reports and reference news. And his work is commendable: talking about litigation is not easy, but he has managed to synthesize it in a single graph to know who sues who in the world of AI. In the center are the technological companies in demand and on the outside, those who demand: from writers to media, platforms and artists. Each category is represented with a color and the larger the circle, the larger the company. There is also a disclaimer: to make the graph look better, when a plaintiff has several open lawsuits, only the main defendant’s lawsuit is shown. Come on, there are many more than we see. Who is suing who. Information is beautiful The map of conflicts On one side, the companies that built AI models, such as OpenAI, Google, Meta, Anthropic, NVIDIA and Perplexity, among others. To another, plaintiffs of all kinds who allege that their works were used without permission or compensation to train systems that have now become their competition. The bottom line is that all the major AI companies are receiving requests from almost all creative categories. Some great cases: Bartz vs. Anthropic. The company led by Dario Amodei agreed to pay $1.5 billion after it was shown that it had downloaded hundreds of thousands of books from unofficial repositories. The court validated the training as fair use, but not the way to achieve it. Kadrey vs. Goal. Mark Zuckerberg’s company won in the training part, but is still on trial for having distributed pirated content. New York Times vs. OpenAIstill in progress. The Times alleges that ChatGPT reproduces its articles almost verbatim, replacing the original source. Disney vs. Midjourneystill in progress: The big entertainment studios fight against the generation of images. Concord, BMG and Universal vs. Anthropicstill in progress. The big legendary record labels sue for reproducing protected lyrics. The US Copyright Office public In May 2025, a 108-page report concluded that there is no universal answer: determining whether the use of works to train AI is fair use requires analyzing each case separately. And not all companies are the same nor are all uses. What is clear is that this system of “asking for forgiveness instead of permission” has a price: Anthropic has shown that it can get away with paying $1.5 billion because its valuation is $183 billion. So the short answer is that today, it has been worth it. The underlying question is whether there will continue to be a flood of lawsuits or whether clearer rules will be established on the use of data and there will be someone with a firm hand and knowledge to apply them.

Ferrari wants your car to charge itself in the sun while parked. One of his patents explains how

by

A few weeks ago, Ferrari dropped a time bomb with its first electric car, Luce. the car has given to talk at lengthand has generated all kinds of opinions. It is also a vehicle that gives us clues about the direction the brand wants to take in this stage of transition that we are going through. But it is not the only one, because if we delve into the intricate world of patents, Ferrari has registered accounts that would raise some eyebrows. One of his last patents registered with the United States Patent and Trademark Office (USPTO) is share the CarBuzz medium, which describes a system of photovoltaic panels that deploy from the roof of the vehicle when it is parked. It is not a typical solar roof and has peculiarities that are worth commenting on. What’s in the patent. The document describe a rollable photovoltaic panel housed in a cavity inside the roof of the car. When the vehicle is stopped and turned off, the panel can be removed through a slot to cover it. According to the technical drawings of the patent, there are two possible positions: one of the panels deploys forward, over the windshield, generating shadow in the cabin; another does it from the rear, under the rear window, oriented at an angle to better capture sunlight. The mechanism uses a U-shaped element and two support rods to extend the panel from its roller. Why do you do it this way and not any other way? The solution may seem complicated (and it is) compared to simply integrating solar cells into the roof, as some manufacturers already do. But Ferrari seems to have its reasons. First, a roll-up panel that is only activated when parking allows the use of a larger photovoltaic surface than would fit on the fixed roof. Furthermore, the patent explicitly mentions the dual purpose of the system, which is to charge the battery and reduce the interior temperature of the cabin when the car is in the sun. Along with this, in the patent is pointed out The system includes sensors and weather data to automate when it is deployed or picked up. Limitations. A solar panel that only works when the car is stationary and in the sun has a very limited range in real life. In the end, the efficiency of these systems depends greatly on weather conditions, the orientation of the vehicle and the exposure time. It is not a fixed place with a large space that allows these losses of efficiency to be counteracted, as is the case in a photovoltaic installation that we can integrate into a house. CarBuzz mention the case of Hyundai, which has been studying this technology for years and that it integrates into some of its test vehicles. The firm stated that its solar roof can replenish between 30% and 60% of the battery per day in ideal conditions, which for a car with more than 300 kilometers of autonomy could cover the average trip to work. But those “ideal conditions” are the exception, not the norm. What it says about Ferrari. As we have mentioned before, the patent appears at a very specific time, as Ferrari has just launched the Luce, its first fully electric car, conceived as a vehicle for everyday use and not just as a sports car for occasional use. It makes sense for the brand to start exploring ways to manage autonomy and charging in different ways than conventional ones. On the other hand, just as points out CarBuzz, adding weight and complexity to the roof goes against Ferrari’s historic philosophy, focused on pure handling and clean design. These are ideas that the brand will have to play with to clarify its priorities in the coming years. However, it should be noted that, at the moment, it is only a patent, not a product announcement. Ferrari, like many other companies, registers technical ideas without necessarily implying that they will reach a production car.

The head of CATL explains why it will still take us a while to see them in cars

by

We have been hearing the industry buzz for years about solid state batteries. These promise more autonomy, faster charging and greater safety than the current liquid electrolyte ones. However, everything indicates that we still have a long way to go until we see them in commercial vehicles. And the president of CATL, Robin Zeng, has spoken in an interview with the Chinese magazine Caijing, suggesting that they are unviable before 2030, and that when they arrive, they will not be for the average buyer. They are not ready. Zeng explained in the interview that, for the production of these batteries to make industrial sense, the industry needs to manufacture at least one million vehicles with them, and that volume does not seem to be achievable before 2030. In addition, the manager suggests that, if ready, they would first target the premium vehicle segment. Technical problems. According to share At CarNewsChina, CATL’s solid-state technology is currently at level four on a nine-point technology maturity scale. That means it remains confined to laboratories and prototyping phases. As the media reports, the main bottleneck is at the solid-solid interface, since to join the components, hot isostatic pressing is applied at 6,000 atmospheres of pressure. The problem is that materials with different densities misalign under that pressure, creating internal resistance and accelerating cell degradation. Other chemicals. With solid batteries still in the lab, CATL continues to accelerate with conventional liquid electrolyte chemistry. In May, the company reached an installed capacity of 33.08 GWhup from 29.06 GWh in April, according to data from China EV DataTracker. The bulk of this volume is supported by lithium-ferrophosphate (LFP) batteries, which in May represented 23.12 GWh, while ternary lithium batteries added 9.96 GWh. For now, these batteries are what keep the industry going. Cost, another barrier. In previous statements, the company recognized that solid-state sulfur cells cost three to five times more than conventional lithium-ion cells. The development of sulfur electrolyte technology alone requires a cumulative investment estimated at 10 billion yuan (about 1.27 billion euros). There are alternatives that don’t wait. Although pure solid state is far away, some Chinese manufacturers are betting on intermediate architectures. From CarNewsChina stands out the alternative from Dongfeng Motor, which plans to integrate into production during the second half of 2026 an oxide-polymer composition battery with an energy density of 350 Wh/kg and ranges of more than 1,000 kilometers. This hybrid approach reduces the total weight of the battery pack by 30% compared to conventional liquid solutions and improves cold performance by more than 10%, according to the company’s testing at -30 ° C in Mohe, where prototypes maintained more than 74% of their nominal capacity. The aerospace sector already uses them. Outside of the automobile, technology advances faster in niches where cost is not a limiting factor. And just as share CarNewsChina drone manufacturer Ehang completed an unmanned flight across the Qiongzhou Strait using a 480 Wh/kg solid-state lithium-metal battery manufactured by Shenzhen Neox. The Chinese industry does not act alone. In parallel, since January 2024 there has been the China All-Solid-State Battery Collaborative Innovation Platform (CASIP), an alliance promoted by the Chinese government which brings together battery manufacturers such as CATL, BYD, CALB, Gotion or SVOLT, along with both state and private car manufacturers. The stated goal is to develop and produce competitive solid batteries with an established supply chain before 2030. According to counted Nikkei at the time, the State also participates with public funds, which makes clear Beijing’s desire not to lose leadership in this sector.

Nothing’s CEO explains why your next phone is going to be more expensive

by

At this point I don’t think it will catch you by surprise, but if so, to summarize: we are living a DRAM memory crisis unprecedented and that, together with the active war conflicts and the situation with AI and data centersare factors that are turning the smartphone industry into a really complicated scenario. The most expensive component of a mobile. Carl Pei, co-founder and CEO of Nothing, has been warning about this for months, and his latest words summarize very well how the situation currently stands. And just as affirms In one of his latest tweets, “memory is now the most expensive component of a smartphone. More than the processor, more than the screen, and can represent more than 50% of the total hardware cost.” pei ya I had anticipated this situation Last January, a few months after we began to see how some manufacturers were modifying the prices of their memory offering, rising up to 300% in some segments. Data center hunger. The large data centers of Microsoft, Amazon, Google and Meta need the same type of memory that phones have (DRAM and NAND Flash) to power their artificial intelligence models. The difference is that hyperscalers (basically Big Tech) pay more, they buy more and reserve production capacity years in advance. According to IDCthe three largest memory manufacturers in the world (Samsung, SK Hynix and Micron) have redirected their production capacity towards the high-performance memory (HBM) demanded by Nvidia GPUs, leaving less supply available for mobile phones. And as the technology analysis firm points out, each wafer destined for an HBM stack for an AI chip is a wafer that will not go to an LPDDR5X module for a mid-range smartphone. By the end of 2025, SK Hynix was already directing 30% of its wafers to HBM; Micron went further and last December said goodbye to Cruciala brand aimed at the final consumer, redirecting all its production to the business market. What the numbers say. The shortage has a direct reflection on prices. Gartner calculate that the combined cost of DRAM and SSD will rise by 130% before the end of 2026, making smartphones 13% more expensive on average compared to 2025. TrendForce situates Global phone production around 1,135 million units this year, a 10% drop compared to 2025. IDC comes to estimate a decline of almost 13% in global smartphone shipments, which would be the largest in more than a decade. And if that were not enough, the average price of a smartphone has already reached $550 in 2026, a hundred dollars more than the previous year, according to share from Memeburn. Who pays the price? Omdia esteem that phones under $100 will drop 31% in sales this year. The entry and mid-range segments, where brands such as Xiaomi, Oppo and others usually operate, they are the hardest hitbecause their margins are very narrow and they cannot absorb cost increases without passing them on to the consumer. Nabila Popal, research director at IDC, claimed that “the era of the ultra-cheap smartphone is over.” The Nothing case as a thermometer. Pei illustrates it with your own product. The memory costs of the Nothing Phone (4a) doubled between the time the company decided to manufacture it and the day it went on sale. And they have doubled again since then. In the life cycle of a single product, the cost of memory has multiplied by four, and it is an example that more brands are living in silence. What changes for the buyer. Pei warns that this year’s sales season, like Black Friday, will not have the discounts to which the consumer was accustomed. Since February, new phones have been on the market with prices up to $100 more expensive than their predecessors. In fact, according to Pei, in India, models above 30,000 rupees (about 272 euros at the exchange rate) have risen more than 7,000 rupees compared to the previous generation. And the forecast is that prices will continue to rise, at least until 2027. For Nothing, it is an opportunity. Pei has been defending for years that design and user experience matter more than specifications on paper, and now the market is proving them right the hard way. “2026 is the year the spec race ends,” he said in January. It is a delicate topic, because if we think about it coldly, we get less for the same price or more than what we already paid, so it can be very easily interpreted as a way of making the user not take into account the technical specifications sheet and let themselves be carried away by what the brand puts in front of their eyes. And now what. The relief in prices will not come until manufacturers have greater production capacity, something that analysts They don’t wait before 2028. Until then, we have two options: either buy now, before prices rise further, or hold on with the device we have. And it seems that update cycles are going to lengthen, and in that context, the second-hand and reconditioned market may gain appeal.

Science has measured how dinner affects sleep and the result explains why you wake up craving sugar

by

Almost everyone has experienced an annoying night tossing and turning in bed after a heavy dinner or fat. Under this pretext, science has gone one step further to demonstrate that the relationship between what we eat and how we rest is completely bidirectional, making what we eat determine whether we are going to rest better or worse. And the most surprising thing is that sleeping poorly can cause us to need to consume more sugar the next morning. A Granada studio. In February 2026 the magazine European Journal of Nutrition public a revealing investigation led by the University of Granada, where researchers monitored the habits of 146 adults with obesity. To do this, they used special watches to analyze accelerometry over a period of 14 days, to later cross-reference the activity data with dietary surveys of what had been consumed throughout the day. Prohibited items. One of the most interesting conclusions reached was undoubtedly the relationship between certain foods and poor rest. And to be clear, the elements that should be prohibited at our dinner are the following: Saturated fats. Eating excess protein and, more specifically, eating red meat for dinner. French fries, or fried foods in general, reduce the quality of sleep. Alcohol is one of the classics on this topic, since, although it generates a feeling of sleep, it destabilizes its quality. Large meals cause slow digestion and cause nighttime awakenings, preventing you from entering into a deep and restful sleep. Highly recommended foods. On the contrary, the passport to restful sleep seems to lie in another type of nutritional profile. Interestingly, carbohydrates, often demonized at night, were associated with better rest in this study. Although we are not talking about sugar directly from the sugar bowl, but rather complex carbohydrates, such as brown rice or potatoes, because help transport tryptophan to the brain. But in addition, the consumption of oily fish such as salmon or sardines is also recommended, since they are rich in omega-3 and especially tryptophan. The reasons. As we see, tryptophan is key in the diet to induce quality sleep, and it is no wonder. Biochemistry tells us that the tryptophan that we ingest through the diet is converted into serotonin and, subsequently, that serotonin is transformed into melatonin, the well-known sleep hormone. And for this chain to work we need very important factors such as vitamin B6, magnesium or zinc. But this also adds to a much less difficult digestion when talking about foods that are barely fatty and that do not require a lot of work on the part of our body and that do not invite reflux symptoms to appear that can be really annoying at night. Specific foods. With scientific support behind it We find the kiwi, since here a trial pointed out that eating two kiwis, one before going to sleep, reduces the time to fall asleep by 35%. But it also increases sleep duration by 13% due to its contribution of antioxidants and natural serotonin. Additionally, green leafy vegetables such as spinach, chard or lettuce provide magnesium and tryptophan. And if vegetables are not for you, we also have eggs, either boiled or in an omelet, which provides tryptophan and vitamin B6, along with the classic grilled chicken breast, which is also an excellent source of tryptophan. The rebound effect. However, the true clinical contribution of the research is to show that this problem is, in reality, a cycle that feeds on itself in a dangerous way. Here the researchers found that when participants experienced a poor night’s sleep, breakfast was marked by a higher consumption of sugars and a lower intake of fiber.

This Norwegian valley has rocks on either side of the river that act like a giant pile. Maybe that explains your ghost lights

by

The Hessdalen lights are a mysterious phenomenon which has been reported in the valley of the same name, in Norway, since 1811. However, it was in the 1980s when they began to be taken more into account, especially in 1984, when the Hessdalen project was established, aimed at monitoring them and trying to explain them. Unfortunately, despite all the efforts that have been put into this, it is currently not known exactly what this is due to. Although it is true that there are some hypotheses. A very disparate phenomenon. Both witnesses who have seen them and scientists who have recorded or photographed them describe the Hessdalen lights as a very disparate phenomenon. Sometimes they are formed at ground level, other times on roofs or at the height of mountain peaks. Sometimes they move more or less homogeneously, other times they move erratically, changing direction for no apparent reason. They are normally white and yellow, although they have been observed in other colors. Some last only a few seconds, while some can remain in the air for more than an hour. Even the shapes vary from an American football to an upside-down Christmas tree. The only thing that most witnesses seem to agree on is that they are about the size of a car. Hessdalen Project. A multidisciplinary team of scientists from several Norwegian institutions launched a project aimed at monitoring the lights of Hessdalen. Since then, they have been monitored thanks to the installation of radioelectric spectrum analyzers, magnetometers, seismographs, photo cameras, Geiger counters and infrared cameras. That is, earth tremors, magnetism, radioactivity and, ultimately, the emission of energy at different lengths of the electromagnetic spectrum are analyzed. This tracking system began operating in 1984 and is still active today. A peculiar hypothesis. One of the most peculiar hypotheses that have been made about the Hessdalen lights is that they could be the visible result of the formation of a wormhole micrometer that connects two points in space time. In reality, this hypothesis was raised in a magazine with little scientific reputation, very given to conspiracy theory and the supernatural, so it is not the most accepted at all. Hypotheses in the air. Thanks to the monitoring of these lights, there are much more plausible hypotheses. To begin with, it is thought that the Hessdalen lights could be due to the decay of radon, a very abundant gas in the Norwegian atmosphere. This disintegration would produce alpha particles capable of ionizing the molecules present in the air and dust, giving rise to structures capable of emitting light, called Coulomb crystals. Hypotheses on the ground. There are also hypotheses that point to the geology of the valley. For example, it is believed that it could be due to the combustion in the presence of air of dust clouds rich in scandium, an element that is abundant in the soil of this Norwegian region. It could also be a piezoelectric effect. This is the effect by which some materials are capable of emitting electricity when pressed or deformed. Quartz, for example, has great piezoelectricity and turns out to be very abundant under the valley floor. Copper is also abundant, which is a great conductor of electricity. And speaking of electricity, a battery effect could also be occurring. On one side of the river in the valley there are rocks very rich in zinc and iron. On the other side, rocks very rich in copper. The former could act as the anode of a battery and the latter as the cathode. In turn, local mines rich in sulfur could be releasing this element into the river, which would act as the bridge of a battery, allowing electricity to flow. If there is electricity, there is light. All these electricity emissions could be causing the ionization of molecules present in the air, giving rise to a process in which light is emitted. It is something similar to what happens with the northern lights, although the origin of the ionizing particles is totally different. The color of light depends on the molecules in the air. That is why it is not always exactly the same, although white and yellow tend to be abundant. In short, it is still not known where these mysterious lights come from, which can be seen both day and night. But that is precisely why they are so fascinating.

Jony Ive, iPhone designer, explains why the Ferrari Luce rejects touch screens

by

You either love him or hate him, but he Ferrari Luce It has not left almost anyone indifferent. The firm’s first 100% electric car is a statement of intent. A commitment to the future that, to do so, gets rid of a good part of its past. And in that setting there is a unique element: the prominence of physical controls and the reduction in the relevance of screens in cars. Why bad design can be lethal. Leo Abrams was publishing these days a video interview in which he asked Jony Ive because of something he had said in the past: “people are dying because of bad design.” What did that mean? In the case of the car, the answer for him was clear: “Multitouch technology is wonderful for a mobile phone, because when you’re using a phone, you’re looking at that phone. But multitouch technology shouldn’t be in a car, I think, because if you have to do basic things, it requires by definition that you don’t look at where you’re going in the car, and that you look at the screen.” Stop looking at the screen so much. For Ive the danger is obvious: if you don’t look at the road, you have a good chance of having an accident. It is a discourse already known in the automotive segment, and since touch screens they became fashionable the debate has always been there. Replacing traditional physical controls with controls that were more typical of a mobile phone or tablet seemed like a recipe for disaster. The Euro NCAP certification body took this into account for your tests: five stars can only be achieved if some functions (turn signals, hazard lights, horn, windshield wipers) ensure the use of physical controls. muscle memory. The problem is not the screen itself, which is tremendously useful for things like GPS navigation, but rather that “touch blindness” that these touch screens impose. Physical buttons allow you to use muscle memory: you can operate them without looking. Touch screens force you to look where you press, which we insist, introduces serious risks while driving. Multitouch technology is not for everyone or everything. Ive also reflected on how any tool has the potential to be used for good and evil “in unpredictable and unexpected ways”, and that is one of the reasons why for him the role of touch technology in the Ferrari Luce had to be almost anecdotal. “I was very fortunate to be involved in the development of multitouch technology. It’s a fantastic technology that makes some new user interfaces possible, but it has to be used appropriately, thoughtfully and carefully.” Result: fewer screens, more touch. The interior of the Ferrari Luce It was the first thing we were able to know about this carand it was already clear at that moment that this was going to be a Ferrari very different from the rest of the Ferraris but that retained that love of touch: the Luce uses physical controls, rotary dials, switches and buttons everywhere. The screens are also present, yes, but touch is clearly a priority over sight, at least when it comes to controlling the vehicle’s options. This is about being better. At the beginning of the interview, Ive made a point: “just because the power source is electrical, one seems to assume that the interface should be digital and that is a big leap and I think that thinking that is presumptuous.” It seems evident that from the beginning Ive and the Ferrari designers and engineers were clear that this car was going to be differentand Ive himself confirms it: “We are trying to solve problems in new ways. Not to be different or new, but to be better.” In Xataka | The new Ferrari Luce is much more than Ferrari’s first electric car. It is a desperate cry to find a new audience
