record

A homemade drone has just exceeded 700 km/h. And with this he has put the official record on the ropes

by

When we think of a drone, we normally imagine a device that takes off vertically, remains suspended in the air and allows us to record impossible shots quite easily. He Blackbird It’s not about that. Its objective is much more extreme: fly as fast as possible. In this race, stability in flight matters less than efficiency at high speed, and so a change in the propellers has given it a surprising boost. The official record remains in the hands of Luke Bell and Mike Bell. According to Guinness World Recordsreached an average speed of 408.60 mph, equivalent to 657.59 km/h, on December 11, 2025, with the Peregreen V4 in Cape Town. It was not their first time: Guinness points out that father and son had already achieved this same record in 2024, with 480 km/h, and in June 2025, with 580 km/h. With that bar on the table, the Blackbird attempt has a very specific reading: it does not replace the official record, but it puts it under pressure. Ben Biggs and Aidan’s drone reached 453 mph, approximately 730 km/hduring a test pass. That fact is the most striking, although it is also the one that needs the most context. For now, what we have is an unofficial demonstration with a huge figure and the question if it can be repeated under verified conditions. A record-breaking race played on the propellers Here is the nuance that separates a spectacular figure from a truly comparable measurement. On the 730 km/h pass there was a tailwind of 54.7 km/h, so the estimated airspeed was reduced to 674 km/h. On the upwind pass, the drone reached about 640 km/h. The average of the two was close to 684 km/h, and that is why that data weighs more than the maximum peak when we try to understand how far the project really went. The key is how those new propellers behave when the drone stops flying like a conventional quadcopter and starts moving like a controlled projectile. The carbon fiber blades have a high pitch angle and that allows them to be more efficient at high speed because they are more parallel to the air that the drone passes through. It is not a free advantage: on takeoff and at low speed they push worse, so the motors have to demand more from the battery in that initial phase. The other important detail is in the serrated leading edge of the blades. As they explain, this shape generates small vortices on the surface of the propeller and helps the air not to move laterally along the blade, but rather to come out backwards to push the drone. It also helps to stabilize the boundary layer, that film of air attached to the surface that influences drag. In practice, it allows working with steeper angles without the propeller losing efficiency and behaving more like a piece that removes air than one that generates thrust. The flip side of pushing a quadcopter to the limit is that problems can also arise. Blackbird lost connection at about 633 km/h, due to a combination of antenna geometry, Doppler effect and signal overload. In the second, the drone ended up damaged after a hard landing, when the batteries ran out a few meters from the ground. The official record remains that of the Peregreen V4, but the Blackbird has made it clear where the next attempt may be. The question, now, is obvious: will they call Guinness World Records to try to certify it? Images | Drone Pro Hub In Xataka | The US vetoed the largest Chinese drone manufacturer.

Japan is suffering a record number of ramen shop bankruptcies. And it is partly the result of the “1,000 yen barrier”

by

The ramen is almost a religion (gastronomic) in Japan. One, yes, condemned to adjust to a certain price range. Although bowls of noodles with soup, meat and vegetables are one of the symbols of Japanese cuisine and a draw for tourists, in the country ramen is seen as a modest dish for students leaving school or workers with a brief lunch break. A sort of ‘worker menu’. So much so that there is even talk of “1,000 yen wall”a psychological barrier to noodle bowl prices. The problem is that Japanese hoteliers have seen their costs increase until they are dragged into a critical situation: in 2024 they registered a record of bankrupt ramen shops and, although the situation improved significantly in 2025ruined businesses still number in the dozens. Bad season for business. That the expense sheet increases while the income sheet is conditioned by a psychological barrier that limits prices can only translate into one thing for businesses: problems. Japan’s ramen restaurants know this well, having been registering dozens and dozens of bankruptcies for years and in 2024 they even reached a record of closures. The data They come from the research firm Teikou and are eloquent. In 2020 there were 54 ramen restaurants condemned to bankruptcy, in 2021 there were 17, a figure that is largely explained by the aid given by the Government during the COVID-19 pandemic, and in 2022 the bankruptcies rose again to 33. The following year there were 53, in 2024 a record of 79 bankruptcies and last year, the latest data available, 59 stores were declared bankrupt. For their study, Teikoku technicians mainly take into account those businesses that accumulated debts of more than 10 million yen (just over 54,000 euros) and have no choice but to declare bankruptcy. The key: the trend. The figure may seem low if one takes into account that throughout the country they are distributed more than 21,000 restaurants of ramen, but it is significant. Last year, in fact, he made the weapons fly due to the record of bankruptcies. The latest data from the sector are somewhat more positive, but are still far from ideal: dozens and dozens of businesses continue to close. However, there is another reason why the figures attract attention: the discourse. Local media and international They have spent time warning of the cascade of closures. There is who warns Furthermore, beyond the balance of bankruptcies, a significant number of establishments that remain open do so in delicate financial health. That is, they remain operational, but they are not well. Struck by costs. Bankruptcy figures may vary depending on the period analyzed, but what does not vary are the analyzes that talk about the causes of the ramen crisis. The diagnosis It is clear: the problem for the stores has been the rise in costs and the limited margin to pass it on to customers. In 2025 Washington Post cited a study from Teikoku Databank that concluded that the sum of the ingredients – including pork, pasta and seaweed –, labor and energy required to make ramen had increased by around 10% in three years. Other calculations They point out that the cost per client grew by 5% between 2022 and 2023. “Prices have been rising over time, but in the last three years they have been incredible,” recognized Tetsuya Kaneko, with a location in Tokyo. The ‘perfect storm’ of ramen. Tetsuya Kaneko assumed in fact that his case was not unique and “everyone in the sector is struggling.” At the end of the day, hoteliers have been forced to deal with a ‘perfect storm’ that works against them: inflationthe rise in import prices due to the weakness of the yen against the dollar and the increase in the cost of energy that had the war in Ukrainewhich also affected the flow of cereals. For three months now, the war in Iran has been added to this panorama, which has made transportation more expensive. “The example of ramen shops illustrates economic trends well because they have a hard time passing on increased costs to end consumers,” explains to the newspaper American Norihiro Yamaguchi, economist specializing in Japan at Oxford Economics. In his opinion, until 2022, consumers were hesitant about any price increase, but the reality is now different: “They have to accept the increase in the cost of living.” For all pockets. As if the situation were not complex in itself, ramen establishments have to deal with another challenge: prices. Or rather, the image that the dish has in the country and the psychological barriers that in a certain way determine its rates. It is not something completely unknown in Spain, where a similar logic operates in the menus of the day of the restaurants. “Ramen has always been a staple food for low-income people, students… I don’t want it to be out of reach,” Kaneko explains.. The “1,000 yen wall”. A quick Google search shows several references, both on blogs and specialized websites in Japanese culture as in diaries generalistswhat is usually called the “1,000 yen wall”, which in exchange amounts to about 5.4 euros. That round number marks the price ceiling that rarely exceeds a basic noodle bowl with broth, meat and vegetables. Or so it was until recently. Faced with the new scenario and the delicate situation to which many businesses have been dragged, those in charge have had to consider a dilemma: cross the 1,000 yen barrier or resign yourself to following in the footsteps of the 72 establishments closed in 2024 and 59 in 2025. Upload with apology included. A few months ago Kaneko I remembered how in 2023 it had to increase its prices by 50 yen, reaching 1,000 for a standard bowl. Another professional in the sector, Taisei Hikage, recalled how rates have changed in a matter of a decade: if 10 years ago there were basic noodle dishes for 500 yen, today the situation is very different. When he opened his own restaurant in 2023, he … Read more

Oviedo has already broken its heat record for May and AEMET warns that this has only just begun

by

Let’s stay with a figure: 34.3. It is, almost certainly, the most important data of the week. On Thursday, May 21, 2026, the thermometers of the city of Oviedo They recorded a temperature of 34.3 degrees. 1.8 ºC more than the highest temperature ever recorded in May in the capital of the Principality. AEMET is convinced that between today and the weekend will be reached again (or even exceeded) this temperature. And yet, this is only a tiny part of the story. Because the real story is that, in a region structurally protected by its oceanic climate, records are being broken in ways we would not have been able to imagine. And that’s without the country being in a ‘heat wave’. What is happening? Although There is some controversy with the namewhat is happening is called ‘heat dome‘. That is, a subtropical anticyclonic ridge, anomalously powerful for this time of year, which is trapping very warm air above our heads. Europe is bearing the brunt, it is true. Countries such as France, Germany, the Netherlands and the British Isles they are seeing temperatures between 10 and 15 degrees above normal. If everything goes as predicted by the models, the May records of half of Europe are going to explode on the 25th of this month. And, of course, we are noticing that. As the haze falls on the Canary Islands (right at the eastern vertex of the dome), a good part of the country will suffer considerable heat. We talk about more than 34 degrees in Asturias and the Basque Country and 38 in the Guadiana valleys. The Guadalquivir valley is already above 35. And, as I say, all this without heat waves. Despite the magnitude of the episode, AEMET does not rate it like a heat wave in peninsular Spain. It is not. We already know that the operational definition requires exceeding the 95th percentile of daily maximum temperatures for the July-August quarter for at least three days and, of course, we are not going to go to that extreme. What does all this heat tell us? Let’s be honest. For Andújar or Badajoz to reach 38 degrees on May 21 is rare, but not exceptional. But for Oviedo to reach 34.3 is a very different thing. It shows, above all, that the Cantabrian coast is beginning to stop being a “climate refuge.” Why is all this important? In addition to an underlying climate issue, this warm episode is important because it is dangerous. The first extreme heat of the year is the deadliest because the population has not gone through the period of physiological acclimatization produced by progressive exposure to summer heat. That is, because it is May and the Iberian summer has truly begun. Image | Tropical TidBits In Xataka | The Gulf Stream is dying.

the “manfluencers” who record women without their consent

by

While some They try to reinvent the smartphone (without success, so far), there is a gadget with AI that is catching on among the general public. AI glasses are becoming more popular and are already being targeted controversies and social debates. Is it ethical to wear a camera on your face that may be recording without others realizing? Not much, especially when those videos are used for extortion. What has happened? In BBC They tell the story of Alice (not her real name) and how she was recorded without her consent at the entrance to a London shopping center. The man was actually a content creator who gave dating advice to other men. She published the video of their interaction and it went viral to the point that it reached the protagonist herself. Alice says she was shocked because the man “didn’t have a phone, he didn’t have a camera pointed directly at my face.” If you want me to delete it, pay me. Alice said she felt humiliated and contacted the account that had posted the video, requesting that it be removed, but the response was not what she expected. The man who had recorded it asked him for payment in exchange for removing the video, since according to him it complied with the platform’s rules. Finally, it was TikTok that deleted the video, but reuploaded it to another account, which has been deleted for violating its rules on harassment and bullying. There is more. Alice’s is not the only case of videos of this type recorded with AI glasses. In a previous reportBBC narrated the cases of two other women who had also been recorded by one of these “manfluencers.” The modus operandi is to approach women to ask for their phone number or start a conversation and then upload it to networks, where they often go viral and generate all kinds of comments. Something similar also happened in Spain, a man filmed hundreds of women in the streets of Barcelona without their knowledge. He ended up being arrested for a crime against privacy. We have also seen how AI glasses are used to cheat on examswhich already has the authorities alert in cities like Valencia. Why is it important. Much of the success of the Ray-Ban Meta is due to the fact that they are normal glasses, which you can wear on a daily basis without squeaking (hello, Google Glass). Their main attraction is precisely what makes them perfect for recording without anyone noticing. Yes, they have an LED light that lights up when the glasses record, but there are two circumstances: the LED can be modified and many people do not even realize that that light indicates that they are being recorded. Reaction. Although AI glasses are still an emerging product category, a wave of social rejection and criticism is already emerging, especially in the US where they are most popular. Many people find them invasive and they don’t feel comfortable if someone is wearing someeven if the LED is off. We have also seen the response of the Chinese startup Even Realitiesglasses without a camera whose selling point is precisely the weak point of glasses with a camera: they do not spy on you.

with a bridge built in record time

by

Satellite images reviewed by the BBC confirm that the first direct connecting highway between Moscow and Pyongyang will be operational in the coming weeks. That is to say, there will soon be a bridge that connects Russia and North Korea by road, materializing an alliance that is reconfiguring the conflict in Ukraine. What is happening. The Khasan-Tumangang Bridge, which crosses the Tumen River on the border between Russia and North Korea, is nearing completion. The satellite images that share The middle shows the structure already united in its central section, along with new access roads, a border control post, support infrastructure and parking areas. The Russian embassy in Pyongyang confirms that the planned opening date is June 19. First time in history. Until now, the only physical link between both countries was the so-called Friendship Bridge, a Soviet-era railway crossing inaugurated in 1959, and whose use for road vehicles was limited. The new bridge is, therefore, the first road link in history between Russia and North Korea. It measures approximately one kilometer in length, has two lanes and is built on concrete pillars with metal openings. It also runs parallel to the old railway bridge. Numbers. According to share In the middle, the crossing has been designed to support up to 300 vehicles and nearly 3,000 people a day. Its total cost exceeds 9 billion rubles, according to Russian state media, which is equivalent to about $120 million. Construction has been rapid, taking about a year, a pace that analysts consider strikingly fast. “The speed of construction reflects the volume of commercial activity between both parties,” said Victor Cha, of the Center for Strategic and International Studies (CSIS). Where does this project come from? The agreement to build the bridge was reached during Vladimir Putin’s visit to Pyongyang in June 2024, when the Russian president met with Kim Jong Un. At that same meeting, both countries signed a comprehensive strategic partnership treaty that includes a mutual defense clause: if one of the two is attacked, the other is obliged to respond. The bridge, therefore, was born under the protection of that pact and has been built in record time. More than concrete. It is inevitably necessary to analyze its geopolitical context. According to data from South Korea, Pyongyang has sent around 15,000 soldiers to fight alongside Russian forces in Ukraine, in addition to long-range missiles and weapons. Seoul also estimates that some 2,000 North Korean soldiers have died in that conflict, although neither Moscow nor Pyongyang have confirmed these figures. In return, North Korea is believed to have received food, fuel and military technology from Russia. “This is an alliance largely driven by North Korean supply of troops, weapons, ammunition and manpower for Putin’s war in Ukraine,” explained Cha about it. What exactly will it be used for? Once open, the bridge will connect the Russian settlement of Khasan with the North Korean town of Tumangang and link directly to the Russian road network, reducing the distance between Vladivostok and the border town of Rason to 320 kilometers. Of course, Russian and North Korean drivers will be prohibited from driving their vehicles into the territory of the other country. In this way, the exchange of goods would take place at the border post itself, transferring the load from one truck to another. “This bridge will offer a very useful route to transfer military material and ammunition, both to North Korea and Russia,” counted Dr. Edward Howell, an expert on Korea at the University of Oxford, spoke to the media. The other side of the coin. Russian Foreign Ministry has described the opening of the bridge as “a truly historic stage in Russian-Korean relations” whose “significance goes far beyond a purely engineering task.” Moscow presents it as a symbol of cooperation in trade, economy and humanitarian relations. But for Western analysts, the reading is very different: a logistical artery designed to sustain a military alliance that transcends the war in Ukraine. “The construction of the bridge exemplifies how North Korea’s ties with Russia aim to continue beyond any end to the conflict in Ukraine,” pointed out Howell. China. It is not just Russia that is seeking to strengthen its physical connection with North Korea. China resumed last month the first passenger train service with Pyongyang after six years of interruption. North Korea, which for decades has been one of the most isolated corners of the planet, is being progressively integrated into the infrastructure networks of its two great allies. “It is fair to say that this connection, before the war in Ukraine, was one of the most dormant links between North Korea and its two neighbors,” Cha acknowledged. It seems that that lethargy has been left behind. In Xataka | While we were looking at gasoline, the Iran crisis has skyrocketed the price of asphalt.

Netflix premieres today one of the best dystopian series of all time and breaks a sadly unusual record

by

When ‘The Handmaid’s Tale‘ premiered on Hulu in April 2017, winning the Emmy for Best Drama when it was still a cult series. Now, a year after airing its sixth and final season, the series lands on Netflixbreaking a record that is as pleasant as it is sadly unusual: it is a series with a very specific production company (owned by Disney), but in Spain it can be accessed on practically all platforms. It’s on Netflix, yes, but also on Disney+ (where you can also see – this time, exclusively – its prequel ‘The Testaments’), Prime Video, HBO Max and Movistar Plus+. The weight of the series It is well understood by reviewing its impressive collection of awards: six seasons, 76 nominations and 15 Emmy wins, including the historic award for Best Drama in its first season, the first ever awarded to a streaming platform. streaming. That first season also won for writing, directing, leading actress (Elisabeth Moss), supporting actress (Ann Dowd) and guest actress (Alexis Bledel). For its last season it only received one nomination, but by then it had already made history. In its terrifying dystopian vision, ‘The Handmaid’s Tale tells us how in the near future, the United States government has been overthrown by a theocratic movement that founds the Republic of Gilead. In the face of a global birth crisis, the new regime enslaves the few remaining fertile women (the Handmaids) and assigns them to elite families to father children through ritualized rape. The series follows the awakening, escape and rebellion of one of these maids. Margaret Atwood, author of the original 1985 novel, stated that nothing in the novel was pure invention: everything had already happened. The repressive Taliban system, which since its return to power in 2021 has denied women access to work, education and almost any form of presence, has been repeatedly pointed out as the most direct parallel with the Republic of Gilead. But in the United States, debates about reproductive rights in different states have continued to fuel the political reading of the series. Nobody is spared. For this reason, the Handmaids’ clothing has become a symbol of feminist protest, thanks to a series that remains as shocking and terrifying today as when it premiered.

The rental market is so broken in Spain that more and more tenants are facing a reality: record overcrowding

by

In Spain he increasingly lives more lonely people. And every time he lives more people crowded also. I know: it sounds contradictory, but that is the curious reality drawn by the studies that are in charge of ‘x-raying’ the country’s homes. As paradoxical, counterintuitive and even ironic as it may be, statistical observatories such as the INE or Eurostat confirm that while a part of Spain is forced to live in overcrowded conditions, sharing a house or even fourththe number of single-person households is growing at such a speed that in a few years they will probably be the most common in Spain. That tells us a lot about how the country, its society, the economy and (also) the residential market are changing. Overcrowded Spain. Among its many functions, Eurostat is responsible for reviewing every year how the overcrowding data from the different countries of Europe. Said like this, the concept ‘overcrowded’ may sound subjective, but its technicians have a clear guideline to distinguish what is (and what is not) a home. ‘overcrowded’. In general terms, a home is considered saturated when it does not have a room for each couple, for each adult or for each two young people of the same sex. In Spain that is a reality they deal with more and more people. Especially if we talk about people who live in rented houses. A percentage: 9.5%. The data from Spain leave two clear readings. The first, positive one, is that in our country the overcrowding rate It is much lower than that of other European nations. At a general level (if we take into account all types of housing, owned and rented, both in the free and regulated markets) Eurostat calculates that 9.5% of the population Spanish resides in ‘overcrowded’ houses. Although in practice this is equivalent to millions of people, it is far from the 16.8% average of the 27 EU countries or the ratio of states such as France (10.8%), Italy (24.3%), Portugal (12.7%) or Germany (11.7%). That’s the positive part. The negative part is how the indicator has evolved. In Spain the overcrowding rate has not stopped growing in the last five years until it is at its highest level in the last decade. For reference, in 2018 marked 4.7% and in 2016 it was at 5.4%. The EU average has advanced at a much slower pace. In fact, it has been practically stagnant for years. around 16.8%a value somewhat lower than that recorded in 2016, when it was around 18%. A tenant problem. The Eurostat data They reveal something else: although there is no market that escapes overcrowding, not everyone suffers from it equally. Its incidence is especially high when we talk about people who reside in homes rented at market prices. That is, without taking into account protected housing. In that case the overoccupation rate shoots up to reach 20.5%. What does that mean? That a fifth of Spanish tenants who have rented houses on the free market live in what Eurostat considers overcrowded conditions. Once again, the figure is below the EU average (23.8%) or the rate of nations such as Italy, but it exceeds the indicators for France (18.6%), Germany (18.3%) or the Netherlands (8.3%). And again too stands out for its evolution. Beyond the comparison with the rest of the EU, the reality is that this 20.5% is considerably above the 12.5% ​​in 2016 and represents the highest value since at least 2014. Spain General overcrowding rate Overcrowding rate among tenants in the free market 2016 5.4 12.5 2017 5.1 12.4 2018 4.7 12.8 2019 5.9 16.3 2020 7.6 18.8 2021 6.4 15.4 2022 6.6 14.9 2023 7.6 17.5 2024 9.1 20 2025 9.5 20.5 What is the reason for this increase? A sum of factors, as stated this week The Country in an analysis on the increase in overcrowding in Spain. One of those (crucial) elements is how the housing market has performed in recent years. Idealistic reveals that in general the price of rents has almost doubled in the last decade, at least if we talk about nominal values (without taking into account the effect of inflation): from €7.7/m2 in April 2016 we have gone to €15/m2. In highly stressed markets, such as the one from Palmathat increase has been even more pronounced. The increase in housing prices (extended to both the rental and purchase markets) directly influences the behavior of families. Not only does it limit the options that those looking for housing can choose from, it also complicates emancipation and assume the rent of an apartment without sharing expenses. Not to mention that the imbalance between supply and demand can lead some landlords to opt for renting single rooms and makes it difficult for families who, after growing up (due to reunification or the birth of children) aspire to a larger apartment. A more populated country. There is another key factor. The increase in the overcrowding rate coincides with the general growth of the Spanish registry. According to the INE, at the beginning of 2026 they resided in the country 49.57 million people. Not only is this 440,000 more than a year before, it also represents “the maximum value in the historical series,” in words of the INE. This growth is also supported by immigration, which broke its own record. In January, the foreign-born population exceeded the ten million of people. Why is it important? Although inflation may have led some families to rent part of their homes to make mortgage payments more bearable, it is not unreasonable to think that this increase in migration explains in some way the rate of overcrowding. The economist José García Montalvo remember in The Country that the foreign population tends to group together in support networks and part of the migrants who arrive in Spain choose, at least at first, to settle in the homes of people they already know. “So where three live, five end up living,” he illustrates. In any case, the phenomenon … Read more

Last year, almost no robots finished the Beijing half marathon. This year one has broken the human world record by seven minutes

by

The half marathon world record is held by Jacob Kiplimo with a time of 57:20 achieved just a month ago in Lisbon. This Sunday a humanoid robot called Lightning ran that distance in 50:26achieving for the first time a milestone that had never been achieved. Robots seemed clumsy and unable to outrun humans, but that is no longer true. And it’s just the beginning. Robots are already faster than humans. In the half marathon held on Sunday, April 19, 2026 in Beijing, the absolute dominators were the humanoid robots. Lightning not only broke the human world record by almost seven minutes: he managed to arrive 17 minutes before the first human runner to cross the finish line. The first three classified They were also Lightning models developed by Honor. From disaster to excellence. The first edition of this same event, the Beijing E-Town Half Marathon and Humanoid Robot Half Marathon, It was an absolute disaster for humanoid robots. Only a third of those who ran it managed to finish the race, they were controlled remotely and ran at a pace much lower than that of human runners. This year things were very different: more than 100 robots were presented and most finished the test, but also almost half ran autonomously and several managed to surpass even the best human runners in the world. This is Lightning. The winning robot measures 169 centimeters, weighs 45 kg and was specifically designed to adapt to complex terrain and move at high speed. Its legs measure about 95 cm and its proportions are designed to imitate the stride of elite human runners. It has a liquid cooling system which curiously has been adapted from the one found on Honor smartphones. Du Xiaodi, engineer in charge of this project at Honor, explained that “Running faster may not seem significant at first glance, but it allows technological transfer, for example in structural reliability and cooling, and eventually in industrial applications“. Not everything went well. The race, however, also had moments in which the robots failed. One of them collided with a nearby vehicle although he managed to stabilize himself and continue walking. The H1 model from Unitree, the most famous humanoid robot manufacturer in China, collapsed as it approached the finish line and had to be removed from the road. One of the Lightning models hit a barrier after crossing the finish line, and some other robots they had difficulties with the curves and unevenness of the route. The event also served as a test bed for batteries, joints, motors and algorithms that control these machines. Industrial applications. Xiaodi mentioned it but also Liu Xiangquan, professor of robotics at the University of Science and Information in Beijing. According to him, these long-distance races allow the resistance and behavior of these robots to be evaluated, something essential for their application in industrial environments. Here not only speed is evaluated, but also the aforementioned resistance, stability or the capacity for autonomous navigation in uncontrolled environments. But a key component is missing. Although the demonstration and milestone is fascinating, what this field needs most is other things. For example, advance manual dexterityperceive the real environment in unforeseen situations and be able to perform varied tasks and not focus so much on repetitive movements. Industrial robots are already good at that, but here we are looking for much more versatility because at the moment these robots They are not able to fold clothes or put the plates and cutlery in the dishwasher with sufficient speed and dexterity. China continues to set the robotic pace. The Asian country has completely devoted itself to the world of robotics. Dominate this segment and its companies They manufacture 80% of global production. In recent months we have seen spectacular demonstrations such as the one Unitree carried out with a dozen humanoid robots at a martial arts show. Sunday’s half marathon is one more element of that narrative and that message that China is leaving to the world: robots are our thing. And in a year, what? Breaking the world record is very striking, but this event tells another story: that of how in just one year Chinese manufacturers have managed to improve their models in an amazing way. If everything continues to improve at this rate, it is difficult to predict what the robots that run the next marathon will be capable of, but it seems logical to think that at this point the athletic ability of robots will be absolutely amazing.

China is building a tunnel under the sea for its high speed. It has already reached a record depth

by

Under the seabed, dozens of meters deep, there is a work that is progressing with a minimal margin of error. It cannot be seen from the surface, but it is part of a railway infrastructure key in southern China. According to CGTNthe country has reached a new milestone in the construction of a high-speed underwater tunnel: the excavation has already reached 113 meters under the seabed. The figure is not minor, because it places the work at a point where the geological conditions and water pressure significantly increase the technical difficulty. This advance is part of a much larger infrastructure that is taking shape in the south of the country. The 116-kilometer Shenzhen-Jiangmen high-speed line is designed to connect both cities in less than an hour, integrating into the rail corridor that runs along the Chinese coast. In this way, the project has entered a particularly demanding phase, in which the tunnel under the Pearl River estuary becomes one of the most technically complex points of the entire work. A section under the sea that concentrates the greatest technical challenge At the center of this phase of the project is the underwater infrastructure that requires refinement of each step. To execute it, the work relies on a large diameter tunnel boring machine developed in China. The machine, known as “Shenjiang-1”, has kept the excavation going continuously, even during festive periods such as Qingming. It not only drills the ground, it also allows progress while the interior lining of the tunnel is being built, a system that seeks to gain efficiency in one of the most delicate points of the route. From there, the challenge stops being just mechanical and becomes conditioned by the terrain. The TBM must traverse 13 different strata, with five types of composite geology and six fault zones along the route. These types of conditions force the operation to be constantly adjusted, because each layer can respond differently to the excavation. In this context, moving forward does not depend solely on the power of the machinery, but also on maintaining control in a challenging environment. Added to this complexity of the terrain is a less visible, but equally determining factor: the pressure of the water at those depths. The tunnel is planned to reach a maximum of 116 meters below the seabeda level at which hydraulic conditions become especially demanding for the machinery and the structure itself. To operate in this environment, the system uses a sludge circuit that fulfills a double function: on the one hand, it reduces friction at the excavation face and, on the other, it transports the extracted material to the surface, where it is separated and reused in the process. While the machine advances, the tunnel is not far behind. Just behind the excavation face, the teams are assembling the prefabricated concrete segments that form the interior lining. Each one measures around two meters wide and nine are needed to complete a ring in a structure that exceeds 13 meters in diameter. This system allows excavation and construction to progress at the same time, reducing time and helping to maintain the pace of execution. The magnitude of this work is better understood when put into perspective. Official information indicates that this section extends over 13.69 kilometers and crosses several waterways at the mouth of the river, located between Dongguan and Guangzhou. It is a key piece within a line designed to improve the connection in the Guangdong-Hong Kong-Macao Greater Bay Area. Beyond the depth already achieved, the project seeks to strengthen regional connectivity and support economic integration in one of the most active areas of the country.

Apple has broken an all-time sales record with the MacBook Neo in its first week. The surprise is absolutely zero

by

Tim Cook himself confirmed it a few days ago in X. And Apple has managed to beat its own record with the help of MacBook Neo In terms of sales, it is the best launch of a Mac for new users in its entire history. The theme is striking to say the least, although it is little surprising considering that it is a significantly cheaper product than the rest of the equipment offered by the brand. Why does it matter? Apple has dominated the premium laptop market for decades, but it has always had a clear ceiling: its entry price. He MacBook Air with M5 part of the 1,199 euros, which leaves out a huge group of Windows PC users, Chromebook or directly without a computer. The launch of the MacBook Neo, at 699 euros (which remains at 599 for students), is Apple’s first serious attempt to conquer that market. And it seems to be working. busy week. On March 11, Apple presented three new computers simultaneously: the MacBook Neo, the MacBook Air with M5 chip and the MacBook Pro with M5 Pro and M5 Max. It was a pretty dense week for the Mac line. A few days later, Tim Cook published in X that this launch had broken the historical record of new Mac buyers, that is, people who purchased an Apple computer for the first time. Although Cook does not break down the figures or specify which model leads the data, the logic points in one direction. The responsible one. The MacBook Air and MacBook Pro have a consolidated user base that periodically renews their equipment. The MacBook Neo, on the other hand, has no previous installed base: it is a completely new product, designed from the ground up to attract those who have never bought a Mac. With a price approximately half that of the Air, it is a profile that fits exactly with that of a buyer making the jump from Windows or a Chromebook. And it should be noted that the Mac has been on the market for decades, but there is still a huge volume of PC users who have never had one, and the Neo seems destined to change that. Who would imagine that a Mac would sell more if it were at a more competitive price… Demand exceeds supply. Another indicator of the Neo’s impact is that Apple is not being able to meet demand, according to they count from 9to5Mac. During March 20, all MacBook Neo models in Apple’s online store had a delivery date between April 6 and 13, according to the media, which means between two and three weeks of waiting for a product launched just a week ago. Normally it is something that usually happens when a new iPhone arrives, but on Mac it is something much less common. Those with an Apple Store nearby may have better luck, although the assortment varies greatly depending on location and color. The industry was already on alert. The impact of the Neo has not gone unnoticed outside of Apple. According to AppleInsiderWindows PC manufacturers have been surprised by both the price and the features of the new laptop. It is not a device for everyone, but it does seem to be for many: it has the A18 Pro chip (the same as iPhone 16 Pro) that, for office automation and navigation tasks it gives you plentyand it comes in a good assortment of colors, with a value proposition that was unprecedented on Mac and that seems to convince many users.
