subtle improvements that refine a compact mobile that already shone on its own

Sometimes I wonder to what extent we are willing to sacrifice the comfort for having The most powerful mobile. It seems that the market has convinced us that “bigger” always means “better”, but not all manufacturers think the same. As we said a while ago: “small” mobiles are not finished. Xiaomi is part of this. This Sunday, in the Mobile World Congress, the Chinese brand has revealed its new Xiaomi 15 family, with the Xiaomi 15 Ultra at the top and the Xiaomi 15 as a more contained alternative but equally promising. Although they have just been presented and are already available in Spain, I have had the opportunity to try the most “compact.” Xiaomi 15 Technical Card Xiaomi 15 dimensions and weight 152.3 x 71.2 x 8.08 mm 191 grams screen OLED LTPO of 6.36 inches Resolution 2,670 x 1,200 pixels Refresco rate: 1-120 Hz Tactile sampling rate: 240 Hz Pico shine: 3,200 nits Pro HDR, Dolby Vision, HDR10+, HDR10, HLG Xiaomi Shield Glass processor Snapdragon 8 Elite Adreno GPU RAM 12 GB LPDDR5X Internal storage 256/512 GB UFS 4.0 rear camera Angular 50 MP, OIS, F/1.6 GREAT ANGULAR 50 MP, OIS, F/2.2, 115º FOV Telefoto 50 MP, F/2.0 Front camera 32 MP F/2.0 battery 5,240 mAh 90W fast charge 50W wireless fast charge Operating system Hyperos 2 connectivity 5G SA/NSA Dual Nanosim Wifi 7 NFC Bluetooth 5.4 Infrared port others Ultrasonic fingerprint reader on screen IP68 resistance Stereo speakers 4x microphones price From 999 euros Xiaomi 15 – 12+512GB Smartphone, Leica Summilux optical lens, Snapdragon 8 Elite, 6.36 “” 120 Hz, Hz, 90W Hypercharge, 90W Hyperchar, charger not included, black (ES version) * Some price may have changed from the last review Small adjustments that lead a mobile already outstanding one step further The first impression I had when I saw the Xiaomi 15 was that this year the company had not risked too much with the design. But, after thinking about it, I realized that it doesn’t have to be something negative. Many brands are committed to evolving their generation product after generation instead of reinventing it. Apple does it with the iPhoneFor example. With that idea in mind, I decided to approach the device with more attention. Was it a discreet but well thought out or simply logical continuity? Sometimes, the most interesting details are not noticed at first glance, but jump when we see calmly. I also wanted to answer the big question: what has really changed on this mobile? The feeling of being before a Premium product It is perceived as soon as you have it in your hand. The aluminum frame of “aerospace grade”, the rounded edges, its 8.08 mm thick and a weight of 191 grams contribute to a careful ergonomics. Xiaomi also ensures that he has distributed the weight in a balanced way to enhance this feeling. Chamber modules in detail: Xiaomi 14 (left) in front of Xiaomi 15 (right) In the back of the device we find a family design, without obvious changes with respect to the previous generation. The photographic module is still located in the upper left corner, housing three sensors. The novelty is in the flash, which leaves this module to be directly on the rear cover, inside a stylized elongated capsule. The back of the Xiaomi 15 white Once again, Xiaomi is committed to collaboration with Leica, the legendary photographic firm that has long reinforces the visual section of its devices. As for hardware, There are no great revolutions: Again, three 50 MP sensors each. However, the AI ​​offers better both in the image processing section and in the zoom. The sides of a black Xiaomi 15 If we stop in the details, a change that is obvious is the finish of the rear. While the Xiaomi 14 opted for a brilliant and striking glass, the new Xiaomi 15 adopts a frosted glass With a more discreet matte finish. In addition, the subtle textured bezel surrounded by the camera module has disappeared in this update. The Xiaomi 15 has rounded edges, a detail that improves ergonomics The matt rear and the aerospace aluminum edges not only provide elegance, but also a key advantage: they do not catch traces easily. For those who enjoy an always impeccable mobile, this finish is a success. Although at certain angles they can be marked, the difference with other models is remarkable. There are much more prone options to get dirty. The Xiaomi 15 come in three colors, black, green and white Xiaomi maintains the same color palette: black, white and green. However, The tones are now softerwhich slightly changes the perception of design. Personally, the green finish is the one that highlights in this model, while white, with its contrast marked in front of the black photographic module, I found the most attractive. On the front we find, once again, with a 6.36 -inch OLED screen, resolution of 2,670 x 1,200 pixels and a refreshment rate of up to 120 Hz. The maximum brightness has risen from 3,000 to 3,200 nits, an interesting increase, although in my fast tests under direct sunlight still does not seem sufficient. We will check it in the Review complete phone. The front of a white Xiaomi 15 News are also in the least visible details. Specifically those that inhabit under the screen. Xiaomi has left the optical footprint sensor behind and makes the leap to a ultrasonic sensorwhich promises a faster and more reliable unlock. In addition, it should work even with wet hands. All this without compromising the safety of the device. A white Xiaomi 15 The mobile also wins in autonomy. The battery rises from 4,610 mAh to 5,240 mAh without the weight. Quick cable charging remains at 90 W and wireless in 50 W. Of course, there is a negative point: the charger is not included in the box, which would lead us to make an additional investment to make the most of it. Since the end of last year … Read more

In 2016, a urologist discovered that a Disneyland attraction helped expel renal calculations. The story was a bit more complicated

In September 2016, David Wartinger (Urologist and Professor Emeritus at Michigan State University) He published a study according to which the Russian mountains facilitated the passage of kidney stones and, of course, the media went crazy. The kidney calculations They usually cause intense pain, bleeding, nausea and vomiting. In many cases they do not even go through the ureter them alone and you have to reduce them to dust with shock waves. The mere idea that a simple walk in a fair attraction could help solve it was a bombing. Of course, the story had a small print. Big Thunder Mountain Railroad. At some point in the late nineteenth century, someone found A colossal gold vein in Big Thundera mountain of the southwest of the United States. Quickly, the small mining camp in the immediate vicinity became a prosperous city and the mountain was filled with an intricate system of trains that moved the mineral from one place to another. No one suspected that Big Thunder was a sacred place for the Native Americans. Or, rather, it was a damn place that the natives avoided as a soul that the devil carried. It was inevitable that, sooner or later, a catastrophe would pass. And it passed. Some speak of an earthquake, others of a sudden flood. Be that as it may, the town was abandoned and the mine was closed until, years later, an expedition discovered that the wagons continued to move through the heart of the mountain without anyone who handled them. No, As Randy Meeks explained to usIt is not a real event: the plot of the most mythical mountain of Disneyland. That’s where history begins. A urologist in Michigan. As Wartinger himself explainedthe idea came unexpectedly. “Basically, I had patients who told me that after getting on a certain Russian mountain in Walt Disney World, they were able to expel their kidney calculations (…) I even had a patient who said he expelled three different calculations after climbing several times” As it seems, this theory did not pay much attention until, already retired, he discovered that other urologists They told similar things. It was then, when he felt the need to put it into practice. He did not do it with people, of course: he did it with a 3D model of a kidney with three calculations. He put it in the backpack, went to Orlando and rode 20 times in the Big Thunder Mountain. And what did you discover? “In total, we use 174 kidney calculations in different shapes, sizes and weights to see if each model worked in the same attraction and in two other roller mountains,” Wartinger explained in Msu Today. Interestingly, Big Thunder was the only one that gave positive results. “In the pilot study, sitting on the last car of the Russian mountain showed a success rate of around 64 percent, while sitting in the first cars only had a successful rate of 16 percent.” A simple curiosity … that quickly took out of context. With the help of the same Wartinger, by the way. As explained in Snopesin the interviews given by the retired urologist went far beyond reporting the results of his study. “If you have kidney calculations, but otherwise it is healthy and meets the requirements of the trip, patients should try it. It is certainly a cheaper alternative to medical care,” he said. The problem is that the basis for this is weak. What really does science say? There is no doubt that, as other urologists pointed out, This preliminary evidence suggests that a roller coaster can help naturally expel (very “) small. But, obviously, there is no empirical basis to recommend it. That is, it is a very striking study that could give an interesting clinical trial. A study that was never conducted. And without which, raising it as an alternative is risky: the experience of riding in that roller coaster with a large calculation can be terrible.

A startup wants to build the “Tesla de los Barco”. His revolutionary idea is to put candles

Transport electrification and the search for alternatives to traditional combustion are priorities for many countries. While Europe and China They bet on him electric car and aviation explores more sustainable fuelsmaritime transport of merchandise continues to depend almost completely on diesel. Although the most Of world trade, it is rarely mentioned in the conversation about sustainability. However, a company is already working on changing this And that solution is an millenary technology: candles. Pollution. To meet the tremendous commercial volume we need at the moment, we use huge boring ships. And, although the focus is put on other forms of transport, the maritime is a significant source of pollution. HE esteem that the sector produces 3% of global CO₂ emissions and other particles that contribute to global warming. Specifically, it is responsible for 15% of nitrogen oxides emissions -Nox- and 13% of sulfur oxides -sox- that humanity produces. He guilty It is the fuel used, with high amounts of sulfur and heavy metals, but the regulations allow ships contaminate up to 500 times more than land vehicles. At full sail. Therefore, measures are being implemented to mitigate the polluting impact Of the great ships such as speed reduction, more respectful fuels either systems carbon capture within the ships themselves. But there are also those who are exploring other ways. Show this is the Yara Birkeland boat That not only works thanks to a cover full of solar panels, but does it autonomously. Another example is a design of the British company Windship Technology that bets on technology thousands of years ago: candle. Or a kind of candle. The ‘Tesla de los Mares’. Presented A few years ago, the True Zero Issation is a ship or propulsion project that allows the CO2, NOX and SOX to eliminate, as well as any other polluting particle, of the navigation equation. The idea of ​​the company is for the ship to work with a diesel-electric energy system and, to ensure that there are no emissions, carbon captors would be installed. In addition, the helmet would be optimized to offer the lowest possible resistance to water and would have software that draws the best possible route taking into account variables such as weather forecast, distance, currents and the state of the sea. But it is clear that what attracts the most attention is the candle system. 21st century candles. Unlike traditional candles, which generate wind resistance to propel the ship in the opposite direction to that current, the Windship design consists of several masts with three wings that what they are looking for is to attract the wind to, next to the electric motor, optimize the movement of the ship. Each of these platforms can be up to 48 meters high, something that adjusts depending on the size of the ship and is mobile, oriented to take advantage of the currents. Challenges. At the moment, there is no ship designed with this base system, and it is not something that seems simple. The reason is that the boring ships have their load surface, precisely on the deck. Except for Roro shipsdesigned as large covered garages, the containers transport their load on the deck, which raises a challenge: the candles would occupy valuable space and could interfere with the port operations. From Windship already comments that the structure of the mast can be folded to facilitate maneuver and that its useful life is greater than 25 years, but it is clear that it is an added challenge for ship designers. For now, who has interested For technology is DNV, an insurance organization in segments such as oil, energy or maritime industry. Superyates. Although these large load ships are heavyweights in naval pollution, where a system like the one that Windship poses in luxury yachts can have more future. David Barrow is the Windship technology director and Comment that, although the strictest regulations have not yet affected the superyates, with the environmental objectives marked By 2050, it is possible that these vessels are also wrapped in the restrictions. Being much lighter than the large charges, a yacht of about 70 meters with three masts of 35 meters each could reach the same speed that current engines provide. That, of course, would lead a redesign in the construction plans so that they are more “dynamic and with better stability. Traditional sailboats. The Windship solution is evident that it is avant -garde, but there is another company that literally bets on candles. By sailboats to transport merchandise, specifically. It’s about Towta French company that completed a pilot trip with its ship a few months ago Anemosa sailboat with carbon fiber masts, traditional candles that are deployed by remote control and two diesel-electric motors. Anemos is the first of a projected fleet of eight vessels that, according to Towt’s calculations, would transport 200,000 tons of merchandise every year, saving with its impulse to candles about 40,000 tons in CO₂ emissions. The ‘anemos’ In the end, to candles or not, it is evident that manufacturers should look for alternatives to current fuels if they want to adjust to restrictions based on achieving the decarbonization objectives. And it would be curious to see non -competitive ships driven thanks to new generation candles.

New honor pad V9, features, price and technical file

Although it has just begun, this edition of the Mobile World Congress (MWC) has already provided us with several pleasant surprises in the field of Android tablets. Xiaomi has presented just a few hours ago its interesting Pad 7 and Pad 7 Proand a few minutes ago the China also Honor has surprised us with a very ambitious tablet that is unmarked from its competitors in several very important sections. I propose that we start taking a look at your screen. Honor proposes a 11.5 -inch LCD panel with 2.8k resolution (2,800 x 1,840 points) capable of working at a 144 Hz soda frequency. It is not bad, although it does not impress (Xiaomi’s new tablets bet on a 11.2 -inch LCD panel with 3,2K resolution). Of course, the PAD V9 tablet screen emits, according to honor, very little blue light, so in theory it should cause little ocular fatigue. And, of tip, it is compatible with IMAX Enhanced content. Honor Pad V9: Technical Specifications Honor Pad V9 screen 11.5 -inch LCD with 2.8K resolution and 144 Hz soda frequency resolution 2,800 x 1,840 points Soc MediaTak Dimensity 8350 Elite 8 core CPU: 1 x Cortex-A715 3.35 GHz + 3 x Cortex-A715 3.20 GHz + 4 x Cortex-A510 2.2 GHz main memory 8 GB storage 256 GB Operating system Magicos 9.0 (Android 15) camera 13 megapixels f/2.0 battery Lithium polymers 10,100 mAh connectivity Wi-Fi 6 Bluetooth 5.2 sound 8 speakers colors White and gray dimensions 259.1 x 176.1 x 6.1 mm weight 475 g price 8 GB + 256 GB: 499 euros Honor Pad V9 11.5 inches 8 GB + 256 GB * Some price may have changed from the last review The bet of this table for AI is total We are going with your soc. The chip by which the honor engineers have opted on this tablet is a MediaTak Dimensity 8350 elite that integrates an 8-core CPU (1 x Cortex-A715 to 3.35 GHz + 3 x Cortex-A715 to 3.20 GHz + 4 x Cortex-A510 to 2.2 GHz). More things. The rear camera has a 13 megapixel sensor, incorporates a sound system equipped with 8 speakers and proposes wireless connectivity Wi-Fi 6 and Bluetooth 5.2. Nothing to object to here. The chip by which honor engineers have op Whatever one of the most surprising characteristics of the hardware of this tablet is its battery. And is that its thickness, only 6.1 mm, has not prevented honor engineers from integrating an ambitious battery of No less than 10,100 mAh. With this figure your autonomy should guarantee many hours of uninterrupted use. And finally, we cannot ignore its benefits within the scope of the artificial intelligence (AI). One of the most attractive functions proposed by this tablet is its ability to move from voice to text in real time with multilingual translation, also in real time. It doesn’t sound bad. In addition, the AI ​​is able to organize our notes with a single click and highlight the key points automatically. On the other hand, we can insert in our formula documents writing them by hand. Or define several templates to distribute the windows that contain the apps at our please. Of course, it is important that we do not overlook that in order to be able to take advantage of some of these benefits we will need to get the digital pencil known as Magic Pen that proposes honor with this tablet. Honor Pad V9: Price and availability This tablet will be available over the next weeks with a price of 499 euros for the 8 GB version of RAM and 256 GB of secondary storage.

We already know why mobile phones with 6,000Mah are not arriving in Europe: there is a clear responsible

He Xiaomi 15 Ultra It is already in our hands. Your hardware is impressive: it has the Best Qualcomm processora camera system that paints spectacular and a software enhanced by AI (which high range can afford to do it). But there is a specification that collided: its 5.410mah battery. In China, the phone is sold with a 6,000Mah battery, a remarkably greater capacity than that of its European twin brother. Daniel Desjarlais, head of communication globally at Xiaomi, has dissipated us personally. We already know why the European model has a smaller battery. The two versions. The Xiaomi Ultra 15 is almost the same as the Chinese model. There is a small difference at the software level, since the Chinese ROM does not have Google services, much less with the new integration with Gemini that they have released on this phone. However, the model that lands in Europe does so with a 5.410mah battery. It is a considerable size, but far from what its Chinese variant offers. Cost savings. The explanation is simple and clear: cost savings. Xiaomi has not given concrete figures on how percent the cost of bringing a 6,000Mah battery device but, at least at this time, is significant enough so that they cannot reach Europe. “The 6.000Mah battery would have led to an improper cost increase in global devices. We must try to find a balance between giving our users everything we can and how much will cost.” Daniel explains that importing phones from China has a cost, and that the company seeks a balance between bringing models to Europe with the best specifications, and that the price does not continue to increase. The Xiaomi 15 Ultra has better speers than last year’s model, but maintains the same price in our territory. Silicon-carbon as ally. There is a main responsible for, finally, the 5,000mAh batteries cease to be the artificial top we had been seeing for years. The Silicon-Carbon batteries They are the new fashion, and allow manufacturers to integrate much more capacity in the same size. This is why they have been able to increase the capacity of the Xiaomi 15 in more than 600mAh compared to its predecessor, and so that the Xiaomi 15 Ultra has some more battery than the ultra 14 (the previous model had 5,300mAh). Companies such as Honor also sell their Magic7 Pro with almost 6,000Mah battery in China, staying only in 5,270mah in Europe. A trend that we hope is ending up reversing according to the costs of this type of batteries are descending over time.

Makes external battery for mobile

There are manufacturers who try to differentiate themselves from original ideas and it is very much appreciated. HMD, the Finnish company that Until recently Nokia’s phoneswe were surprised during this Mobile World Congress with a device as simple as it is striking. And useful. Because in the end that is what we all look for. May technology help us. Next to Fusion X1 have presented the new HMD Amped Buds. Wireless headphones with noise cancellation. They offer high resolution audio, 95 hours of playback and have 10mm controllers. But it is none of these characteristics that make it unique in the market. The first with reversible wireless load. The HMD Amped Buds are the first headphones whose load base also serves to load the mobile. To date, the case served to load the headphones themselves, but HMD has concluded that that battery can be used for something else. Compatible with any mobile with wireless load. And what better than loading the mobile. Although stylized, the HMD Amped Buds case has reverse wireless load, to be able to load any mobile that admits wireless load. The case is very light. It has a weight of 78 grams, a thickness of 14.3mm and a height of 74mm. To get an idea, it is somewhat less than half of a standard mobile. And the case of magnetically hooks on the back cover of the mobile. We simply approach and voila, we already have an external emergency battery. Perfect for an emergency. Let’s not think that we will have an external battery with a great capacity. It is simply to load the headphones (up to 11 times) or to load the mobile at a timely moment. Its capacity is 1,600 mAh. The battery also has a USB-C port, in case we simply want to load the cable mobile. Headphones manufacturers, take note. After having been able to try these headphones, whose price is 199.99 euros, I must say that they seem to me to follow closely. I have not had the opportunity to check its sound quality, but to try its ultrafine load case and test the wireless load with a pixel and an iPhone. The result has works as one expects. To the first. In my case I usually use the JBL Tour Pro 3 And they seem to me a very curious option for their external screen. But in fact it does not seem to me a sufficient justification to have that large load case. If all manufacturers take note of this idea of ​​case with reversible wireless load, we will win. Since we have to have a battery for our headphones, what less that also serves us for the mobile. In Xataka | Someone has created headphones that do not need adapter to charge. They do it for photosynthesis

Recent studies suggest that cocoa was not born in Mesoamerica, but in the current Ecuador

Talking about cocoa is talking about your Impact on Mesoamerican societies. Cocoa arrived in Mexico at some point in 1900 AC and esteem That it was the Olmecs who domesticated the plant at some point between 1200 and 400 AC was the pillar of different Mesoamerican cultures and became more than a food. However, recent studies have challenged that idea. The reason? Neither olmecs, nor Maya, nor Aztecs: the first who used cocoa were the Amazonian cultures that bound with Ecuador and Colombia. We go in parts. The food of the gods. As we say, cocoa is something cultural In Mexico. The Maya They considered which was the “food of the gods” and used it as a sacred drink. It was very different from the sweet we know today, since it was prepared with cocoa in pieces, flour, chili, cinnamon and hot water, resulting in a dense and bitter mixture. Had presence In its rituals, but it was also used as an offering to ask for something from the gods, it could be used as a currency and even as a status symbol. The Aztecs They refined Something else the formula, since they roasted the grains, grind them and mixed with ingredients such as vanilla or aromatic flowers. Subsequently, they added hot water and thus the Techocolat. Hello, Ecuador. But the two cultures had something in common: it was not a simple food. Although cocoa knew that it appeared in the high Amazon, in regions that are now Ecuador and Colombia, the domestication of the plant occurred thanks to Mesoamerican societies. But, as we say, recent studies They have put this belief upside down. Researchers and archaeologists at the University of Berkeley, from the University of Columbia Britanic and the French Development Research Institute According to him firsttraces of cocoa uses in containers of about 5,300 years ago indicate that the civilizations that inhabited these tropical jungles already gave use to cocoa well as food, or as an offering. This indicates that its use dates back about 1,500 years to which we considered the first in the Mesoamerican civilizations. Archeococin. It all started with the discovery of elaborate ceramics that would have belonged to culture May-Chinchipewhich occupied the Western Amazon about 5,500 years ago. Michael Blake is one of the researchers and commented on Science that those vessels were similar to those used to make cocoa. That was when he asked his colleagues “Is there any possibility that these vessels were used to make cocoa?” And the answer was “nobody has proven it.” He assumed the task and, by scraping different parts of the containers, they found that there were remains of starch with a composition that is only seen in the pods of the seeds of the cocoa tree. They also found theobromine, a compound present in mature cocoa seeds. Thus, they could affirm that this civilization was already doing cocoa routinely before Mesoamerican cultures. Evidence of the first areas that used cocoa Domestication or non -domestication? Rosemary Joyce is a researcher at the University of Berkeley who has studied for years the origin of cocoa and its deep relationship with Mesoamerican cultures. It is important because he commented on this joint study between several universities and, although he found unquestionable that this Ecuadorian culture was already working cocoa, he asked if they really managed to domesticate the plant. Because there is an important difference between using the seeds found sporadically and really having an industry supported by the plant. This domestication of cocoa is something that is also thoroughly being investigated and, before the study we mentioned, it was published other that dated domestication 3,600 years ago in Central America. Blake and his colleagues are convinced that it was the inhabitants of South America who domesticated the plant due to the amount of different artifacts in which they found traces of cocoa elaborations. Impact on Mexican identity. Joyce, who was not very convinced with the new theory of domestication in Ecuador, commented in a article Subsequent that “after decades of research, new discoveries show that one of the most widely repeated statements, such as cocoa cultivation began in Mexico or Central America, should be reviewed.” And a question that may arise is how these discoveries affect Mexican identity, which for hundreds of years consolidated their predecessors such as those who dominated the cocoa plant and began using their fruits to make food. The answer is … that something like this should not be a cultural earthquake. That traces of the early use of cocoa are traces in another totally different area is an archaeological achievement and that continues to teach us about the civilizations of the past, but it will “invent” that invented it, the relevance of cocoa between Mesoamerican cultures is indisputable, being a pride For Mexico. Spread. Now the mystery is to match that first crop in the area of ​​Ecuador and the arrival of plants to Mesoamerica. Joyce considers that, with these revelations, “a new stage begins in the history of cocoa: to link its early history in South America with that of Central America and Mexico.” In the 2018 Science study, the researchers already affirmed that the search for that relationship is something that they should study more thoroughly ”, since the current mystery is how cocoa trees made that trip of thousands of kilometers until they reached Central America. Cocoa seeds They lose quickly their viability, so they are not easy to transport and that are reproduced in a new land (especially with the methods they had thousands of years ago). In the end, the finding does not take importance to the role of cocoa in the Mesoamerican culture, but it does enriches the history of the plant itself and gives us clues to throw for future investigations.

How China has advanced the US on its presidential plane

Every time the president of China, one of the main economic and military powers of the world, travels abroad in a State visita safety operational complex is activated. From transport to personal protection, everything is designed to minimize any risk and ensure that the diplomatic agenda runs without any setback. In the most complex trips, China displays a Boeing 747 fleet. According to simple flyingwhile an airplane is reserved for Xi Jinping, another transports its accompaniment personnel and a third is responsible for the load, including the presidential limousine. A logistics scheme reminiscent of the United States uses in this type of displacement. China and the United States choose Boeing Boeing is going through difficult timesbut that does not prevent him from manufactured some of the most emblematic aircraft in the world. A clear example is the Boeing 747in service since 1970 and still considered a reference in aviation. Both the United States and China have chosen it for the transport of its leaders, being a key piece on international trips. President Donald Trump has two Boeing 747-200b (VC-25), in service since the 1990s. These aircraft have been deeply modified to function as true control centers in the air, with private suites, offices, meetings and advanced communication and defense systems to guarantee VVIP level security. Xi Jinping travels in a Boeing 747-8, a more modern version than used by the president of the United States. This aircraft was delivered In December 2014but it was not until 2016 when it received its VVIP configuration, with specific modifications for presidential transport. Of course, the information about this point is extremely scarce. What is known is that, although the logo of China Airits use is reserved exclusively for Xi Jinping and acts as its air operations center. As we indicated above, the Chinese government also asks the state airline to have commercial aircraft for official functions when necessary. China uses a Boeing 747-8 for the transport of personnel and a Boeing 747-400 load for logistics support. In the latter the Hongqi N701Xi Jinping’s armored limousine, considered the Chinese version of the American “The Beast”, which in the case of the US moves into a C-17 Globemaster IIIa military load plane built by Boeing. Although there is no confirmed replacement plan, China could replace its presidential plane of the American Boeing with an alternative of its own manufacturing. The country has already developed with SUCCESS THE COMAC C919a narrow fuselage plane, and works on the C929a wide fuselage model that could become a viable candidate. The United States has been trying to replace its Boeing 747-200B presidential by Boeing 747-8, but the process has been full of delays. In this context, the Boom Supersonic CEO, Blake Scholl, has suggested that The White House leaves 747 and bet on a special version of the Overtureits supersonic development plane.

Only 17% have a passport

That Japan lives A tourist boom unprecedented was reflected last December, when the Nation registered an absolute record of international visitors reaching the 3.49 million tourists In a single month, closing a year that reached the 36.87 million visitors. Interestingly, this massive arrival of people in the country does not have its counterpart in the Japanese. In fact, the rate of citizens who have a passport to travel is very small. 17%. Although the Japanese passport is considered one of the most powerful in the world, with access without visa to more than 190 countries, the figure leaves doubts: only 17% of the population Japanese has one, a surprisingly low figure compared to other developed nations. In countries like the United States and the United Kingdom, for example, the percentage of citizens with a passport is 50% and 85% respectivelywhich shows a notable difference in the disposition of the Japanese to travel abroad. According to data from the Japan Ministry of Foreign Affairs, in 2024, 3.7 million passports were issued, which represents an 8.8% increase compared to the previous year, but remains 15.2% lower than in 2019, before the pandemic. Factors behind the data. Historically, the passport rate in Japan has been low compared to other advanced economies, maintaining Between 22% and 24% In the 2010s. However, this number collapsed during the pandemic and has not shown significant recovery signs since then. Several causes are pointed out, in addition to family economies. One of the key factors is paradoxical: The devaluation of Yennot stop Attract tourisminternational trips have increased and the disposition of the Japanese to leave the country. In addition, the prolonged travel restrictions imposed during the pandemic conducted the population to travel, especially to young people. Loss of competitiveness. According to the Japanese Association of Travel Agents (JATA), the interest of young people for traveling abroad has weakened too much, so much that they think it could have long -term consequences for Japan’s global competitiveness. Its president, Hiroyuki Takahashi, has expressed concern about the gap between entry and exit tourism, warning that the country must correct this severe imbalance to maintain its international influence. Impact on education. The decline in the provision of the Japanese to travel not only affects tourism, but also to student mobility. In fiscal year 2023, Only 58,162 university students They participated in short and medium -term exchange programs, half of the levels prior to the pandemic in 2018 and 2019. But there is more. The number of Japanese students who carry out long -term studies abroad has also fallen dramatically. In 2022, Only 41,612 students traveled abroada figure much lower to the maximum historical of 82,945 in 2004. A phenomenon that contrasts with the growing number of foreign students who Japan choose as educational destinationwhich reinforces the idea that Japan is losing presence in academic and professional exchange circuits. Solutions to stop the trend. Given this situation, experts have suggested that the government take proactive measures to promote international trips among young people. Among the most outstanding proposals is offer free passports To those who travel abroad for the first time, which could encourage more people (especially young people) to explore the world and strengthen the role of Japan in the global stage. And meanwhile: tourism. We said it at the beginning, while the number of Japanese who seem willing to travel outside their borders is ridiculous compared to its population, to the nation Does not stop people. In fact, the rise of tourism has provided a vital impulse to the country’s economy, turning the expenditure of visitors into the second largest export of the nation, only behind the automotive sector and above the electronic component industry. In 2024, travelers spending reached a 8.1 billion record (51.57 billion dollars), a 53% increase Regarding the previous year. A country that looks inward. In the end, the data show a clear reflection of Japanese society. Japan faces A worrying decline In the disposition of its population to travel abroad, with economic, generational and social factors that have reduced the international mobility of Japanese. Although the country continues to receive a disproportionate tourists and foreign students, their international projection is weakened by the lack of exchange in the opposite direction. Hence, the passport data is not much less trivial, and that the government seeks measures to encourage travel and learning outside its borders. At stake is the competitiveness of the nation.

Xiaomi’s weapon to compete with the best in AI for mobile

Within the framework of the Mobile World Congress 2025, Xiaomi has announced great plans for 2025. Xiaomi 15 Ultra is one of them and, together with Xiaomi 15make up the new high range for this year. These two phones arrive with Hyperai, the interpretation of the Chinese manufacturer. Xiaomi has come something after his rivals to integrate multiple functions of AI so natively, but says the saying that better. I have been able to try some of these first -hand functions, so I’m going to tell you what Xiaomi has implemented on these phones, and what to expect from this first stage. This is how Xiaomi money earns – they attract you and catch you The novelties of Hyperai Hyperai’s novelties are divided into seven blocks. In all of them there is a common point: it is a native integration. In other words, they are deep integrations at the system level and it has been sought that the experience be as far as possible to use a third -party service. That said, this is what you should know about Hyperai in Europe. Gemini: Integration with Gemini is completely native. It works as a system assistant, it is invoked with the ignition button and, the most mold, you can read the content of all our apps if we give permission. This allows you to make summaries, translations, and others. Writing with AI: We can change the style of the message, make summaries, review texts, etc. Gallery editor with AI: We can improve the clarity of the photos with AI, make generative expansion of them (such as the adobe tool), delete objects, or create videos with AI. Voice recognition: Transcripts, distinction between speakers, summaries, translations and custom labels for each speaker. Interpret conversations with AI: Face to face interpretation, automatic language recognition, translation templates. CALL INTERPRETE Subtitles with real time Xiaomi’s AI is quite similar to view on the rest of the phones that use the Nano Gemini model: translations, text improvements, editions in the gallery … Those that require Internet connection, such as the expansion of images, also require Xiaomi account. The deletion of people is improvable. Generative for edges. After trying some of these functions, I am clear that Xiaomi’s AI is in its first steps. In this example, quite easy by the way, I wanted to eliminate the person from photography. The result is somewhat inconsistent. In the second example I wanted to fill in space in photography. If we expand, we see that elements such as the fork contain errors. Writing functions are available in apps such as WhatsApp. Some others are native, such as interview transcription in their recorder app. Regarding text corrections, they work quite well. It is a useful function for professional emails and work environment. Transcripts work relatively well (with some errors, of course), but the phone takes a long time to process the results. I would like this processed to be done in the background to expedite the process. Xiaomi has reached AI a tuño late, but the integration promises. Not taking some year of experience makes it end up noticing a certain distance in front of some of its competitors, so the following updates have an important work ahead: reach the level of the best in the market.
