For 45 years we thought we understood how stars like our Sun rotate. A Japanese supercomputer has just cast doubt on it

by

Understanding how stars rotate may seem like a technical detail, but it is actually a central piece to understanding their evolution. For 45 years, theoretical models held that Sun-like stars would eventually change the way they rotate as they aged. The idea was that, as it lost speed over billions of years, the spin pattern would reverse and the poles would rotate faster than the equator. Now, new research from Nagoya University suggests that that prediction might not come true. The findings. The work, published in Nature Astronomysuggests that solar-type stars could maintain the same rotation pattern that we observe in the current Sun throughout their lives. That is, the equator would continue to rotate faster than the polar regions even as the star slows down with age. The simulations carried out by the team indicate that magnetic fields play a decisive role and could prevent this regime change that was taken for granted in theoretical models for decades. How a star like the Sun actually rotates. Unlike the Earth, which rotates as a solid body, the Sun is made of extremely hot plasma. That causes different regions to spin at different speeds. In the case of the Sun, the equator completes one revolution approximately every 25 days, while the regions near the poles take about 35 days. This phenomenon is known as solar-type differential rotation. For decades, theoretical simulations predicted that this pattern would not be permanent. As stars age and their global rotation slows over billions of years, the plasma flows within them should reorganize. Predictions indicate that there would come a time when the behavior would be reversed: the equator would rotate more slowly and the poles would rotate faster, a regime that the researchers called differential anti-solar rotation. The unexpected role of magnetism. The new simulations suggest that the scenario predicted by theoretical models for decades may not come to pass. According to the results of the study, stars similar to the Sun would maintain the same type of differential rotation throughout their lives. Even if the star slows down with age, the equator would continue to rotate faster than the poles, rather than reversing the pattern as proposed in previous simulations. A supercomputer on stage. To reach that conclusion, the team turned to FugakuJapan’s most powerful supercomputer, installed at the RIKEN research center in Kobe and operational for shared use since March 2021. With its help, researchers carried out an extremely detailed simulation of the interior of solar-type stars. Each simulated star was divided into about 5.4 billion calculation points, a much higher resolution than that used in previous work. This level of detail is important because previous simulations worked at much lower resolutions. Under these conditions, the magnetic fields tended to disappear artificially within the model, which led to underestimating their influence on the internal dynamics of the star. In the new simulation, however, the magnetic fields remained stable and showed a clear effect: they help prevent the reversal of the rotation pattern. The implications. Understanding more precisely how Sun-like stars rotate is key to interpreting their magnetic activity over time. This aspect is related to well-known phenomena on our own star, such as the approximately 11-year solar cycle that regulates the appearance of sunspots and episodes of magnetic activity. A better understanding of these processes could also help improve stellar evolution models used by astronomers to study distant stars.

the Spanish space startup grows with Japanese money

by

PLD Space has closed a Series C round of €180 million led by Mitsubishi Electric. With this injection, the Elche company exceeds the 350 million raised in total and has a clear path to carry out the first demonstration flight of its rocket Miura 5 before the end of 2026. Why is it important. Spain has very few technology companies capable of raising this type of money on a global scale. PLD Space has not only achieved this, but has done so by attracting a top-level Japanese manufacturer that is not coming to make a financial bet but to secure access to launches for its clients in Asia. That difference between a financial investor and a strategic investor changes everything. Between the lines. Mitsubishi Electric has also signed an MOU with Lockheed Martin to collaborate on geostationary defense satellites. That the same week in which he signs that agreement he also leads this round in PLD Space is no coincidence. Japan is building a chain of access to space so as not to depend on anyone, and PLD Space fits as a provider of low orbit launches for the constellation of satellites that that ecosystem needs. For the Spanish company, this means support that goes beyond capital: it is a seal of industrial credibility. In figures: 180 million euros raised in Series C. More than 350 million in total accumulated financing. Planned capacity of 30 launches per year by the end of the decade. The Miura 5 can place up to 1,080 kg in low orbit. Target production: 4 rockets in 2026, 6 in 2027. The context. Europe has had the problem of access to space on the table for years. The delays of Ariane 6 and the dependence on American launchers have made it clear that the continent does not have a mature private alternative. He European Launcher Challengewhich calls for a test flight of a higher-capacity rocket before 2028, has acted as an accelerator for PLD’s roadmap. The company already designs the Miura Nextdesigned precisely to meet that institutional challenge. The big question. PLD Space has proven that it can raise money and that it can fly hardware. He Miura 1suborbital rocket, completed its first launch in October 2023. But the jump to orbital is different. Many launch startups have raised hundreds of millions and have not reached orbit. The real test begins when the Miura 5 takes off from Kourou, whose facilities should be ready in July. Until then, money buys time, but not guarantees.

A Japanese toilet company has been manufacturing key parts in the chip industry for years. And now it is going to be key in AI

by

Toto, world famous for their toilets with a trickle that we usually miss so much when we return from Japan, has been quietly manufacturing key components for the semiconductor industry for decades. Just like account Financial Times, an activist fund has focused on that part of its business, and the market is starting to pay attention. What has happened. Palliser Capital, a UK-based activist fund, has sent a letter to Toto’s board of directors arguing that the advanced ceramics the company works on are being ignored and underestimated by the market. The fund, which owns a stake among the 20 largest in the company, according to share from FT, calls Toto “the most underrated and overlooked AI memory beneficiary.” What is important. Toto is not just a bathroom company. Since 1988 it has been manufacturing the so-called ‘electrostatic chucks’ in series.‘ (electrostatic jaws), high-precision ceramic components used in the manufacture of NAND memory chips to hold silicon wafers during the production process, controlling temperature and avoiding contamination. This business, which they fit within their “advanced ceramics” division, already represents around 42% of the company’s total operating profit, according to data from Bloomberg. The connection with AI. He data center boom for artificial intelligence has skyrocketed the demand for memory chips. Companies like Meta, Amazon or large memory manufacturers (SK Hynix, Samsung, Kioxia) are accelerating their production to face a widespread shortage. That translates into more demand for the components that Toto manufactures. The company’s ceramic technology is also specially adapted for cryogenic etching, a process that is expected to gain popularity as memory chips become more complex and layered. Business tips. According to share The fund also criticizes that Toto is not explaining well to investors the importance of this segment and that the allocation of internal capital is not prioritizing this lucrative sector. The fund proposes that the company expand its ceramics business, sell cross-stakes in other companies and make better use of its 76 billion yen in cash (about $496 million). If Toto did all that, Palliser estimates the stock could rise more than 55%. The market had already started to move. Toto shares have accumulated a revaluation of more than 60% in the last year. Just like share Bloomberg, at the end of January, after the support of Goldman Sachs, which raised the value to buy pointing to the memory shortage as a tailwind, the stock rose 11% in a single day, its biggest rise in five years. Be careful with the warnings. The idea that Toto would have that competitive advantage before other competitors can be at that level comes from Palliser himself, who has an obvious interest in making that narrative credible. Tom’s Hardware points out that while electrostatic jaws play a real role in advanced manufacturing processes, whether that translates into sustained growth still depends in part on large memory manufacturers committing to expanding production and, for now, they are being cautious faced with the risk of oversupply if the AI ​​market cools. The phenomenon is not exclusive to Toto. Japan has a long history in chip production, which has led companies with very different profiles to develop businesses related to semiconductors almost without anyone noticing. Just like share Bloomberg, Ajinomoto, known for its broths and its mastery of umami, makes insulating films for chips based on its expertise with amino acids. Kao, a cosmetics company, has a silicon wafer cleaning business. The AI ​​business is revaluing companies that, a priori, had nothing to do with it. And Toto is the latest example of this.

There’s a reason why the Japanese don’t need to dust as much as we do. And you can apply it easily

by

When I was little and living in Switzerland, there was an unspoken rule that we all knew: the shoes They didn’t go beyond the doormat. It was common to see small shelves outside the doors, on the landing, where footwear that had walked on the street was abandoned. For us it was the norm, but when we crossed borders, that custom faded. Today, however, the situation seems to be changing globally. What we previously saw as a cultural curiosity of Japan or a Nordic eccentricity is beginning to make sense in the rest of the world. The contrast is fascinating. While in many Western homes cleaning is understood as a reaction (cleaning what has become dirty), in other cultures it is a preventive lifestyle design. In Japan the secret is not to clean for hours, but to prevent dirt from getting cross the threshold: “Cleaning is not a reaction, but a life design based on prevention.” This philosophy even extends to the air they breathe; Japanese residential ventilation technical documents highlight the critical importance of creating “air passages” by opening opposite windows to expel suspended particles, an obsession with environmental hygiene that invariably begins at the front door. And it’s not just a matter of visual perception. A study from Macquarie University in Sydney, puts it in perspective: until 60% of the dust and the dirt that accumulates inside a house comes from outside, and enters precisely through our feet. The architecture of custom Why is the world divided between those who barefoot and those who don’t? The answer lies in a mix of climate, architecture and philosophy. In Japan, the border is physical. According to the digital media Nipponthe houses have the genkana specific area at the entrance with a step called agari kamachi. This step marks the sacred boundary between the “outer world” (dirty) and the “inner world” (clean). Furthermore, traditional Japanese architecture uses floors tatami (straw mats), a delicate material that would be destroyed by rigid street shoes. In the Anglo-Saxon world, resistance it’s cultural. Journalist Jeff Yang tells in The Guardian a revealing anecdote about his Taiwanese aunt, who told him a lapidary phrase when she saw him enter wearing shoes: “When you enter my house with shoes, you are walking on my heart.” This clash illustrates the division: for some it is respect; for others, as indicated Real Simplewhere only 31% of Americans always barefoot, is an uncomfortable imposition. In Spain, the story is different and has its own peculiarities. There is no deep-rooted tradition to take off your shoes when entering. Historically, doing it in someone else’s house could even be interpreted as a lack of education or excessive trust (“taking too much confidence”). Unlike Nordic or Asian countries, Spain relies on reactive cleaning, something that users on discussion forums such as reddit rsummarize with humor and irony: “We can afford that custom because we invented the mop.” However, the trend is changing after the pandemic. More and more hosts are imposing the “zero shoe” rule for hygiene. It is the case of the influencer of lifestyle Patricia Fernández who, cited in Readingsassures that “removing your shoes at the entrance is your number 1 rule”, always offering comfortable options or baskets with slippers for your guests. Beyond the visible dirt, taking off your shoes has a profound psychological and symbolic impact. It’s not just hygiene, it’s a transition ritual. Dr. Manuel Viso explained that taking off your shoes sends a powerful signal to our brain: “Let’s change the environment, relax, we’re home, we’ve left work behind.” It is a physical switch for mental disconnection, how to change clothes. From an energy perspective, Feng Shui expert Gloria Ramos details in Interior Magazine that the main door is “the mouth of Qi“(vital energy). Leaving your shoes lying around or entering with them blocks that energy and the well-being of the home. Even the way you do it matters, in Japan etiquette requires not only taking off your shoes, but turn them so that they point towards the door (ready for departure) and do so without turning your back on the host, a gesture that denotes respect and consideration towards the community that inhabits that house. Science tips the balance decisively This is where the cultural debate collides with microscopic reality. If you thought your shoes were clean because you didn’t step in mud, experts have bad news. “99% of the shoes analyzed test positive for fecal matter,” pharmacist Álvaro Fernández flatly states. in The Aragon Newspaper. This is because we walk through streets where there are invisible remains of animal excrement and dirt from public toilets. Microbiologist Jonathan Sexton, from the University of Arizona, confirm in Very interesting that almost all soles harbor bacteria such as E.coli (present in 96% of cases) and Clostridium difficilea bacteria that causes serious intestinal problems. But it’s not just bacteria. According to The Conversation, Shoes carry pesticides from gardens, lead from urban dust, and carcinogenic asphalt sealants that end up in the air in our living rooms. It is important not to fall into alarmism. Although shoes are centers of dirt, they are not the only culprits. A published study in Scientific Reports warns that mobile phones are also “dangerous microbial platforms“that harbor a wide spectrum of organisms, often resistant to antibiotics, and that we constantly carry on our faces. It is another reminder that objects such as cell phones or kitchen sponges can have as much or more bacterial load than footwear. Still, experts like Kevin Garey they clarify thatalthough for a healthy adult the risk of infection from the floor is low (since we do not live at ground level), the recommendation is strict if there are crawling children or immunosuppressed people at home. The trend is clear: the frontier of the doormat is hardening in the West, but with our own style. we don’t have genkanbut we have learned to adapt our halls. More and more homes are incorporating benches, wicker baskets or narrow shoe racks … Read more

The Nintendo DS was the best-selling console in the history of the Japanese manufacturer until now. It’s easy to guess who has surpassed her

by

The Nintendo Switch has become the best-selling console in the history of the Japanese company, as revealed by Nintendo in its financial report of February 3, 2026. With 155.37 million units sold until the end of December 2025, the hybrid system has surpassed the 154.02 million of the Nintendo DS, which held the record since its discontinuation in 2013. Two proposals. The data gain more weight considering that the Switch debuted in 2017 with a price of $299.99 (exactly double the $149.99 of the DS in 2004) and not has officially dropped in price in its eight years of commercial life. The concept of the DS (two screens, one of them touch) represented a risky bet when the industry prioritized graphical power. The console found its audience in sectors outside of traditional video games, with titles such as ‘Brain Training’ and ‘Nintendogs’ that attracted users with the same casual profile that the Wii had conquered. Added to this was the DS Lite, launched in 2006, which represented 61% of the system’s total sales: 93.86 million units. The Switch arrives. In 2017, the Switch was double the price of its portable predecessor. Its hybrid concept (functioning as a desktop console connected to the television and as a portable device) eliminated Nintendo’s traditional division between home and mobile platforms. And without price cuts: the OLED model, launched in 2021 at $349.99, meant a net increase in the market positioning of the system. Different pricing policies. The pricing strategy of both consoles differs significantly. Adjusted for inflation, the $149.99 DS in 2004 andThey would be equivalent to approximately $240 in 2024. The DS also experienced reductions during its life cycle, reaching $99.99 in 2011. The Switch, in contrast, has maintained its base price for eight years, something unusual in the consumer electronics industry. The accumulated inflation since 2017 has reduced the real value of the price by approximately 20%. For comparison, the PlayStation 2 dropped its price from $300 to $100 in less than a decade. But the Switch unifies two segments: while the DS competed exclusively as a portable platform (coexisting with the Wii and Wii U as home consoles), each Switch unit captures both the traditional home console and handheld audiences. The difference: the software. Beyond hardware, software performance reveals a gap between both systems. According to data from November 2025the Switch has sold 1,452.79 million software units throughout its life cycle, compared to the 948.76 million that the DS reached at the end of its production. A difference of 53% in favor of the Switch that indicates a greater commitment on the part of its user base. Put another way: each Switch owner has purchased an average of approximately 9.4 games, compared to 6.2 for DS users. The Switch catalog, which includes ports and remasters of titles previously exclusive to other platforms, has reached an audience that goes beyond the traditional Nintendo. PS2 objective. The Switch is still below the absolute industry record: Sony’s PlayStation 2 maintains the position of best-selling console of all time with figures that exceed 160 million units. This brand has generated some controversy after Sony updated its historical data including sales that were not previously listed in its public records. To reach that figure, the Switch would need to sell approximately 4.63 million additional units. However, Nintendo’s current projections contemplate only 750,000 more units until the end of the fiscal year. Besides, Switch 2 It has already sold 17.37 million units. The coexistence of both models on the market could accelerate the withdrawal of the original hardware.

There is a material on which the future of the iPhone and AI depends. And almost everything is manufactured by the same Japanese company.

by

More than 100 years ago two Japanese textile companies called Fukushima Boseki Co., Ltd., and Katakura Seishi Iwashiro Bosekisho they joined forces to become Nitto Boseki Co. Ltd, also known as Nittobo. A century later we have encountered a giant on which a critical material for the future of our chips depends: glass fabric. Technological glass artisans. The Japanese company was the first in industrially producing carbon fiber. They did it in 1938, almost right at the same time as Owens Corning Fiber Glass in the US. Later, in 1969, they developed the “crystal fabric” or “glass cloth” (glass cloth), a material that began to be used in printed circuits Hello, T-glass. That material evolved and in 1984 they launched their T-glass, an even more specialized glass fabric that began to be used as a substrate in chips of all types. This material is different from the common fiberglass like that used in surfboards or in insulation solutions. Thus, it has a very low coefficient of thermal expansion, which ensures its good performance even when the chips are operating at maximum performance. Japan, we have a problem. As indicated on Nikkeiexperts warn that the lack of this material has become a major obstacle to chip manufacturing and the advancement of AI in 2026. Nittobo is practically the only company in the world capable of manufacturing this glass with the necessary quality. Its glass fabric is extremely thin, bubble-free and heat-resistant, which has made it a fundamental part of chips such as those used in iPhones. Apple, in fact, was one of the first major technology companies to reach an agreement with Nittobo to use this material. Everyone loves Nittobo. The good performance of this material has now made companies like NVIDIA, Google or Amazon also demand T-glass for their chips, and that has generated a worrying competition due to inventory that is quickly depleted and it is not clear that it can cope with demand. Apple asks for help. The situation is so tense that Apple has sent some managers to Japan and has even asked the Japanese government to intervene to ensure supplies from Nittobo. Once again the objective is to guarantee the launch of its key products, and at Nikkei they point directly to the expected foldable iPhone. The fiberglass fabric is a critical layer on the chip substrate and ensures that everything works perfectly even under heavy workloads. Source: Nikkei. Capacity will grow, but not immediately. At Nittobo they know very well what the situation is like, but they can’t do anything to remedy it, at least in the short term. A company executive quoted in Nikkei indicates that “if we do not have additional capacity, it means that we do not have additional capacity no matter how much pressure is put on Nittobo. The way I see it, the situation will only improve significantly when Nittobo’s production increase becomes a reality in the second half of 2027.” Looking for alternatives. Apple and Qualcomm are looking for plans B, and their initiatives to find new suppliers in China or Taiwan are already underway. However, the demand for the quality of this type of material is very high: an error in the quality of the glass of the chip substrate cannot be repaired, and would ruin entire batches of components. AI causes chaos again. We already saw it with memories: the AI ​​industry needs immense quantities of DRAM and NAND memory chips, and that has now meant that the rest of the world is suffering from a huge rise in prices. The same thing is happening with this glass fabric: AI chip manufacturers have an exaggerated demand for this material, which harms the rest of the “traditional” chip manufacturers and, therefore, the users. bad business. And as happens with memories, in the end the material is sold to the highest bidder, which are usually companies like NVIDIA that have exceptional profit margins. That leaves consumer electronics manufacturers in a vulnerable position and with declining sales forecasts. Nittobo does not want to saturate the market. And as happened with the memory market, Nittobo does not want to oversize its business in the face of this demand and prefers to be cautious. Japanese suppliers already suffered losses from overstocks in 2022, so they are now reluctant to expand their factories aggressively. It is precisely the same speech that Micron made, which already suffered from excess inventory after the pandemic: although they could now manufacture more memory chips, for them that means risking history repeating itself.

Chinese fighters have targeted Japanese fighters over Okinawa. Japan’s response has been forceful: an archipelago of missiles

by

The tension between China and Japan has entered a cycle of accelerated deterioration that is no longer limited to diplomatic exchanges or formal protests. In recent weeks, the western Pacific has been the scene of maneuvers increasingly aggressive in which the lines between deterrence, warning and provocation become dangerously blurred. In the last few hours the most serious episode to date has taken place. A strategic rivalry. It all started on the weekend, with the lighting with fire control radar of Japanese fighters by J-15 aircraft from the Chinese aircraft carrier Liaoning near Okinawa, a situation that has set off all the alarms in Tokyo. The gesture (an act iunequivocally hostile in military parlance) comes at a time when Japan has committed to reinforce its presence in the area around Taiwan and the Ryukyu island chain, a decision that Beijing perceives as a frontal challenge to its regional ambitions. The spiral is worsened by the statements of Prime Minister Sanae Takaichi, pointing out that an attack on the strait could activate collective defense Japanese, a phrase that China has elevated to the rank of strategic provocation. Radar, aircraft carriers and a risk. Aerial interaction near Okinawa fu much more an isolated incident: it marked the first time that Japan officially disclosed a radar lock Chinese about their fighters. The Japanese Ministry of Defense registered about a hundred of takeoff and landing operations of Liaoning aircraft, in parallel to two episodes in which the J-15 fixed their firing sensors on Japanese F-15s, forcing the latter country to immediately deploy its own combat air patrols. China responded accusing Japan of interfering in their exercises, alleging that it had previously delimited the maneuver area. Chinese aircraft carriers and destroyers moved through the Miyako Strait, one of the sea corridors connecting the Pacific to the East China Sea, while official Chinese media they ridiculed Japanese defensive capabilities and warned that any move toward a more active military role “would lead to its own destruction.” The language, accompanied by real maneuvers which combine naval presence, air patrols and psychological pressure, defines an environment where any tactical error could lead to a crisis. Liaoning Ryukyu as an advanced shield. Faced with this escalation, Bloomberg told that Japan has undertaken the largest military reconfiguration since the Cold War, articulated around a concept that analysts have called the “missile archipelago”. Yonaguni, the country’s westernmost island, has become a surveillance and electronic warfare outpost just a stone’s throw away. 110 kilometers from Taiwan. From 2022, after the salvo of Chinese missiles that fell near its coasts, Tokyo has multiplied the installation of anti-aircraft batteries, long-range radars and response units amphibian distributed throughout the Ryukyu chain. The military presence in Kyushu is also increasing, with deployments of F-35s and long-range missiles. At the same time, the government has started to prepare to the local population with briefings that reveal both the magnitude of the challenge and the growing concern among citizens who vividly remember the trauma of the battle of okinawa. The militarization of the region, although supported by a majority of young Japanese, continues awakening misgivings between sectors that fear that a conflict in the strait will turn their islands into the first line of fire. Japanese military in Okinawa Fight for historical legitimacy. we have been counting. The operational tension is added to an equally volatile front: the historical dispute. Chinese state media has reactivated narratives that question Japanese sovereignty over the Ryukyu, reinterpreting the postwar period and selectively citing statements of 1945 to present Japan as a nation whose sovereignty “is to be determined.” Beijing takes advantage of these references to reinforce its claim about the Senkaku and to argue that his view on Taiwan has a historical legitimacy that Japan cannot contradict. Tokyo responds by appealing to Treaty of San Francisco and to the existing international legal framework, but its effort to maintain stability collides with Chinese pressure, which combines repressive diplomacy with psychological operations aimed at local communities. In other words, the historical dispute is not rhetorical: it feeds the perception in Japan that the conflict with China is not temporary, but deeply structural. Taiwan in the shadows. The link between Japanese security and the fate of Taiwan is today explicit. The doctrine collective defense revised in 2015 allows the country to intervene if Japan’s survival could be compromised, and security analysts they point out that a hypothetical American operation to defend the island would require the use of Japanese bases. Tokyo’s refusal to cooperate with Washington, in such a scenario, would put the alliance itself at risk, making Japanese participation almost inevitable. China is fully aware of this and concentrates its efforts on fracturing the perception of inevitability, putting political, military and psychological pressure to erode the Japanese margin of decision. On that board, the new electronic warfare units in Yonaguni and the missile batteries distributed throughout the archipelago, they could become, if necessary, key nodes in an integrated attack chain between Japan and the United States, which would make them priority targets for a Chinese offensive in the initial phase. Uncertainty. The result of these dynamics is a western Pacific that advances towards an area permanent frictionwhere each movement is interpreted as a dress rehearsal and every political statement is magnified as a strategic notice. The air raidsnaval exercises, the militarization of the islands and the historical dispute between great powers converge in a reduced geopolitical spacedensely populated and highly symbolic. For Japan, the crossroads It is complex: reinforce its defense without reigniting domestic fears about militarism, coordinate with the United States without becoming an automatic target, and respond to China without setting the region on fire. For Beijing, the key is in maintaining the pressureexpand its margin of future action in the Taiwan Strait and fragment the strategic unity of its adversaries.

There’s a reason Vigo is advertising its Kawasaki Christmas. One that has nothing to do with Japanese tourists

by

If you walk around Kawasaki these days (lucky you) you will probably come across an image that will catch your attention, one that has little to do with Japanese traditions and landscapes or with the avalanche of tourists that the country of the rising sun suffers. What will probably make you jump is finding a sign in the middle of Kanagawa announcing Christmas in Vigo, a mupi with a photo of XXL luminous tree of the Galician city and a message that invites you to travel the 11,000 kilometers that separate both towns. It could be an anecdote (one more related to the Vigo festivals), but that image tells us a lot about the fever for decoration Christmas that Spain experiences. Vigo Christmas in Japan? That’s how it is. It was the mayor of Vigo himself, Abel Caballero, who was in charge of showing it on networks. On Tuesday he hung up a photo in which a promotional poster for the Olympic Christmas is seen in what looks like the street of some Japanese city. The advertisement shows garlands, the XXL luminous tree erected in the heart of Vigo and a message in Japanese. “Christmas in Vigo is already in Japan,” Caballero wrote in his tweetwhich is already on its way to 220,000 views and 650 likes. Is it a surprise? Not really. In October Knight has already advanced that this year Christmas in Vigo would be announced with 820 posters distributed throughout (almost) the entire world. Most of those mupis (629) would be distributed across thirty Spanish cities, especially Madrid, Malaga, Bilbao and Seville, and another 142 were reserved for neighboring Portugal. The rest would travel the world. The Council boasted that it would take 15 to Paris, 10 to Rome, the same number to New York and 14 to Kawasaki. “This time Christmas will be in Japan for the first time.” Is it the first time? More or less. The jump to Asia is a novelty, but in 2024 Vigo already surprised to some tourists with promotional posters distributed in cities such as London, Paris, Rome or even the Big Apple. “I thought it was a mirage. I was seeing this in the distance and I couldn’t believe it,” joked in X Héctora reporter who encountered a mupi in the middle of Manhattan that read, in large golden letters, “The World’s best Christmas is in Vigo.” How much do these posters cost? In October, when he announced the new campaign, Caballero assured that at least this year’s is “free” and “costs nothing” to the City Council. Last year the Vigo newspaper Metropilitango.gal pointed that the mupis had been installed after reaching an agreement with JCDecaux. But… Who visits Vigo? If we base ourselves on studies on hotel occupancy by the INE, basically Spaniards and visitors from other areas of the EU, especially Portugal. Of the 537,500 travelers counted throughout 2024, 62.7% resided in Spain and 23.9% in one of the remaining EU countries. Of these, Portugal was the most popular market, with almost 77,000 tourists. Among the countries analyzed by the INE, the United States (14,800), Germany (11,800) and Italy (11,200) followed, far behind. From Japan, the market on which the City Council has now set its eyes, only 700 visitors who ended up staying in hotel establishments in the city. And at Christmas? The photo is not very different from the rest of the year. According to the data provided By the Vigo City Council, during Christmas 2022-2023 tourism was mostly national. That campaign was still marked by the shadow of the pandemic, but the data is conclusive: the City Council assures that some 5.3 million visitors arrived in Vigo and that the main foreign nationality was Portuguese, with 140,118 people, 2.6% of the total. French, British, Italians and Americans totaled 68,400. The hotel occupancy data from the INE show a somewhat different picture. In December the institute counted only 62,900 touristsof which 62% were Spanish and 30.5% Portuguese. The sum of French, Italians, British and Americans in fact barely exceeded 1,100. It is not surprising if one takes into account the limited supply of connections that Peinador, Vigo airport, has (right now Aena reports only five routes). Is there Japanese tourism? If we base ourselves on the INE, no. In December 2024, the INE did not count not a single Japanese visitor in the hotels of Vigo. In addition to how complicated and expensive it is to fly between Japan and the Galician city, this absence is largely explained by the behavior of Japanese tourists. Although the country is recording a record arrival of foreign tourists, the number of Japanese traveling abroad still quite below from pre-pandemic data. In fact in June Turespaña I trusted in which the influx of Japanese to Spain recovers its “pre-COVID” levels this year. Why advertise there then? In view of these data, why has Vigo distributed 14 mupis by Kawasaki and 10 in New York? Does Caballero aspire to attract tourists who live on other continents, thousands of kilometers away? The Consistory speaks to show Galician Christmas to potential tourists from other countries, but the measure is probably explained with another word: virality. Caballero’s tweet is a good example. In just a few days his photo of mupi has achieved several hundreds of thousands of views on X and has made headlines on media from Spain. Just as their estimates do about what Christmas means for Vigo: between 800 and 1 billion euros of economic return with a deployment of 6.3 million “visitors” in just two months, which is more than the total number of tourists who stay in hotels in Galicia in a year. The 14 mupis of Kawasaki may see them only a small portion of the 1.5 million people who reside in that Japanese city, but of course they have reached, via networks and media, thousands of people who live in the market that really interests Vigo: the rest of Spain and (especially) Galicia. Does virality … Read more

We have been searching for dark matter for 90 years. Now a Japanese man believes he has found his “fingerprint”

by

Since Fritz Zwicky suggested the existence of dark matter in 1933, the reality is that it has been one of the great ghosts of modern physics, generating many debates about its existence. The little we know indicates that this matter is there because we see how its gravity pushes galaxiesbut we have never been able to see it or touch it. It is invisible. Or at least, that’s what we believed until now. And to ‘see’ this matter you have to be a true superhero, since it does not emit, absorb or reflect light. Something that makes it completely invisible to telescopes around the world. But it is not something that is a small part of what surrounds us, but which makes up 85% of the total matter in the universe. But now there is hope to have more information about this great mystery of physics thanks to a study Professor Tomonori Totani of the University of Tokyo claims to have found the first direct evidence of this elusive substance. He has not seen it directly with his own eyes, but he has detected the “smoke” of his gun: a very specific gamma ray signal emanating from the halo of our own Milky Way and that eerily coincides with theoretical predictions of how dark matter behaves. A large amount of data. To understand the discovery, you have to look at the sky with gamma ray eyes. Totani has used a total of 15 years of data accumulated by NASA’s Fermi Gamma-ray Space Telescope (LAT). But the important thing was undoubtedly knowing where to look: in the galactic halo. That is, the ‘quiet’ outskirts of the Milky Way, excluding the galactic disk to avoid interference. What he found when cleaning the background noise was surprising: an excess of gamma rays with a very specific energy peak, located at 20 billion electron volts (20 GeV). The importance. So far so good, but… Why is it important? Basically, because it doesn’t fit what we would expect from normal astrophysical sources, like pulsars or supernova remnants. However, it fits like a glove for the WIMP theory. This is a theory that basically suggests that dark matter It is made up of WIMPs (Weakly Interacting Massive Particles). According to physical models, when two of these particles collide, they annihilate each other, releasing a cascade of energy in the form of gamma rays that would be detected in the universe now. And that is their conclusion: the detected signal is compatible with WIMP particles that have a mass of 500 times that of a proton. This would, therefore, be the fingerprint that gives the most information about dark matter, although it does not stop there. The shape is not a point on the map, but a soft, spherical halo that surrounds the galaxy, just as dark matter is distributed in the cosmological simulations that physics has made. The same goes for consistency, since the signal persists even when different background models are used and other known sources of noise in the universe are removed. There are precedents. This isn’t the first time someone has yelled “Eureka!” In the past, excess gamma rays have been detected at the Galactic Center (known as GCE), but the scientific community has tended to think that this signal comes from undetected millisecond pulsars, rather than dark matter. The key to Totani’s study is that he has looked where no one was looking in such detail. By moving away from the center and analyzing the diffuse halo, it is where he has found a much cleaner signal that does not invite so many doubts about its origin. There are still doubts. The study itself admits that the calculated cross section (the probability of interaction) is higher than the upper levels established by the observation of dwarf galaxies, which are often used as scale for dark matter. This means two things: either our models of the density of dark matter in the Milky Way are incorrect (which is possible, since there is a lot of uncertainty in the profile of the halo), or we are looking at a new and unknown astrophysical phenomenon that mimics dark matter. A great mystery. If this finding is confirmed, we would be facing one of the greatest discoveries in physics of the 21st century. It would confirm that dark matter is composed of particles that we can detect (and not primordial black holes) and open a new door for physics. go beyond the standard model. But as we say, this still needs to be verified by a second laboratory such as the Cherenkov Telescope Array Observatory (CTAO) that may have the ability to detect these gamma ray spectral lines.

Ghibli and more Japanese studios demand that OpenAI stop using their works. The reason: the Sora 2 videos

by

In Japan they seem to be tired of images generated with artificial intelligence that resemble, perhaps too much, the mythical works of Japanese origin. We are referring, of course, to images and videos created with AI that seek to reimagine any photo, person or character with “Ghibli style” or similar. An anti-piracy organization in Japan has demanded that OpenAI cease what they claim is a copyright violation. Japan studies against AI. CODA is a Japanese anti-piracy organization that includes companies such as Studio GhibliToei Animation, Bandai, Toho and Square Enix. The organization has published a letter demanding OpenAI stop using its members’ original content to train Sora 2, the OpenAI tool responsible for generating realistic videos with artificial intelligence. Some of Studio Ghibli’s most legendary films. (Images: Studio Ghibli) In your letterCODA (whose acronym stands for Overseas Content Distribution Association) claims to have confirmed that “a large portion of the content produced by Sora closely resembles Japanese content or images.” This, according to the organization, would be the result of having used copyrighted content to train artificial intelligence. In Xataka OpenAI has just made a move after its separation of assets with Microsoft: it has signed an agreement with Amazon for $38 billion What Japanese studies ask for. CODA’s demands are clear: that OpenAI not use its members’ content to train its artificial intelligence model. And also, that OpenAI respond to the demands and complaints of the companies that are part of the Japanese organization about the Sora 2 videos. {“videoId”:”x9hhg44″,”autoplay”:true,”title”:”The TRUTH of AI – This is how ChatGPT 4, DALL-E or MIDJOURNEY works 🤖 🧠 ARTIFICIAL INTELLIGENCE”, “tag”:”webedia-prod”, “duration”:”1173″} The government also pressures. In mid-October the Japanese government already had spoken against OpenAI’s use of copyrighted content to train its artificial intelligence. Minoru Kiuchi, Japanese minister responsible for intellectual property strategy in the country, asked OpenAI not to violate the copyrights of Japanese intellectual properties. According to Minister Kiuchi, manga and anime are “irreplaceable treasures” that Japan offers the world. 2025, the year of “Ghibli-style” images. Last March OpenAI enabled the image generation based on GPT-4oand quickly “Ghibli-style” or “anime-style” images became extremely popular. However, the claims of CODA and its members, in addition to the Japanese government’s request, are especially directed at Sora 2 and its video generation capabilities. In Xataka OpenAI has turned ChatGPT into mainstream AI. In the business world the game is being won by its great rival Although the results are far from perfect, social networks have been filled with these types of unofficial videos made with AI, which for companies such as Bandai Namco, NHK, Wowow, Aniplex and many others represents a violation of their copyright. At the time of publishing this article, OpenAI has not yet responded to the Japanese studios’ request.
