China already has its “flying truck.” The HH-200 has just completed its first test flight

by

China has just put into the air one of those machines that, by concept and ambition, do not go unnoticed. It is not a new fighter jet like the J-35Abut rather a commercial unmanned aerial system for transportation, completed its first test flight on April 15. There is still no logistics network deployed, but there is a movement that allows us to understand where the Asian giant wants to move in the pilotless air transport of goods, especially within the framework of its commitment to the so-called low-altitude economy. First flight. After the entire development phase, the program has already left paper behind. CCTV places the inaugural test in Puchengin the province of Shaanxi, and explains that it lasted for 22 minutes, with correct operation of the onboard systems and stable evolution of the device during the journey. To be precise, this is the first real flight evaluation, and it has been completed satisfactorily. The figures of the device. Once the test is confirmed, the next thing is to take a closer look at what kind of aircraft China has in its hands. It is a system with a square section fuselage, high wing, double engine and double boom, with dimensions of 12.2 meters long, 16.8 meters wide and 3.7 meters high. In the operational section, it boasts a maximum load capacity of 1.5 tons and a maximum range of 2,360 kilometers. Furthermore, according to official information, it is capable of reaching a maximum cruising speed of 310 kilometers per hour. The logistics part. Beyond dimensions or scope, one of the keys to the HH-200 is how its operations on the ground and in flight are planned. China News assures that the system has been designed with civil aviation standards and that it can perform the flight intelligently and autonomously from start to finish, with obstacle avoidance functions supported by AI. Added to this is a direct passage fuselage and a rear configuration designed to facilitate loading operations, allowing work with pallets, loading platforms and conventional forklifts, to the point that two operators could complete loading or unloading in five minutes. Where do you want to operate. The device is not only designed to move goods from one point to another under ideal conditions. Instead, it has a strong environmental adaptation capacity and can execute missions on short runways, high-altitude airports, extreme temperatures and adverse weather. China News gives us some interesting concrete examples: cargo routes in coastal and border areas, internal logistics routes between specific points and operations between islands in Southeast Asia, before opening the door to uses such as emergency rescue, remote sensing or agricultural and forestry tasks. From trial to market. After this first milestone, the next step will not be an immediate implementation, but an additional testing phase. It is expected that the vehicle will continue to accumulate flight tests before its eventual entry into service, an important nuance to avoid confusing initial technical success with operational maturity. Even in this scenario, according to China News, the project has 20 order intentions and closer cooperation with several firms. We have to wait to see if we will see the HH-200 beyond the testing scope. Images | CCTV In Xataka | Boeing has surpassed Airbus after years behind. That doesn’t mean I’ve regained control.

run 20 km to churn your own butter. We have put it to the test

by

Just when I thought the culture of running I could no longer invent more excuses To go out and devour kilometers, the algorithm has decided to merge training with cooking recipes. To put you in situation, I was doing scroll calmly on Instagram and suddenly I came across what I consider the last barrier to fitness: runners that make butter while they run. They have named him the churning and burning (something like “stirring and burning”) or, simply, the butter runs. Can it be real? Apparently, yes. It all started in February of this year with American content creator Libby Cope and her partner, Jacob Arnold. In the video, Cope ask a simple question: “We Googled it and, as far as we knew, there were no previous runners who had successfully made butter. So we said… ‘Okay, shall we be the first?’” In it reel She is seen pouring a carton of liquid cream and salt into an airtight bag. “You might be wondering why,” Cope says to the camera. “The real question is: why not?” Since then, the phenomenon has exploded globally. A quick look at Instagram shows us an army of runners imitating the feat on accounts like saral.fit, margot_outdoor, lib_claire, rachlzw either alexladikoff. gonzo journalism Faced with such an avalanche of content, in Xataka We couldn’t sit idly by, but we didn’t want to get dirty either. So we turn to our hero without a cape: my partner Javier Lacort. Javier, always willing to sacrifice his sports team for investigative journalism, accepted the challenge without blinking: “I’ll do it,” he said. We owe him, at the very least, an eternal breakfast. The conditions of the experiment were the following: Javier went out into the street to run 20 kilometers with an entire 500 ml brick of liquid cream on his back. The weather: clear skies, 51% humidity and a temperature of 13ºC, although with a treacherous thermal sensation of 8ºC. My partner opted for a pragmatic and very much our approach. While American pioneers recommend using airtight bags Ziploc heavy-duty, Javier simply poured the liquid cream into a regular plastic shopping bag. With a few secure snap knots, he placed it directly into the pocket of his hydration vest. The goal was to see if the force of the impact over 20 kilometers would be enough to whip cream. But, before seeing the result, what does science say? How does running turn a liquid into a spreadable solid? As detailed by the Food and Agriculture Organization of the United Nations (FAO), the principle is pure physics: The constant churning process causes the fat globules present in the cream to collide, clump together and end up separating from the remaining liquid, known as whey. Come on, the same thing they did nomads centuries ago by galloping with milk sacks hanging from their pack animals, only now the pack animal is wearing carbon fiber slippers. Today, the runner It’s the human mixer. However, the results vary greatly. Get butter depends on several factors: the distance (most run between 5 and 10 kilometers), the intensity of the stride (the more bounce, the better) and, fundamentally, the percentage of fat in the cream used. The process and the verdict Javier completed his 20 kilometers and, after leaving his vest on a park bench with the air of having survived a true dairy odyssey, the verdict was clear. Upon opening the bag, he confessed: “It smelled wonderful, honestly.” In the images that he gave us of the process, the evolution can be clearly seen. After 20 kilometers of impact against the asphalt, the macro photos reveal that, without becoming a solid and consistent block of butter, the cream had been whipped and presented a lumpy and thick texture. Why did Javier get a thick whipped cream texture instead of a block of butter like those on TikTok, despite having run a considerable distance? The answer is in the weather. Scientific American magazine has the key: Temperature is crucial. If it is too cold, the fat molecules harden and fail to group together to form solid clumps; if it’s too hot, the mixture turns into soup. The ideal temperature is room temperature. With a thermal sensation of 8ºC, Javier had the thermometer against him. In fact, other runners who attempted the challenge on snowy days failed in the same way. Given what has been seen, for those who want to replicate it, the pioneers leave some vital advice. Libby Cope recommends running for at least an hour, using cream with 35% fat and, as a rule of thumb, always use an airtight “double bag” to prevent your back from ending up looking like a clandestine cheese factory. Other users recommend loosening the hydration vest a little so that the bag bounces more, or choosing routes with hills, stairs or uneven terrain. And the vital question: is this edible? The short answer is yes. In fact, eating it has become the official goal of the race. The challenge has generated a small post-workout ritual: open the container to check if there is butter and spread the fresh result on a piece of bread as a snack recuperator. It’s the perfect ending to the social media video. Culinary creativity has not taken long to appear. One of the runners, Irene Choi, is no longer satisfied with the basic recipe, but rather practices he habit stacking (stack habits) creating flavored butters. They add sea salt, herbs de Provence, garlic or even honey before going for a run. Choi went so far as to make a “honey butter and corn juice” that he called “an excellent use of my time.” From a more cynical (and brilliant) perspective, columnist Emma Beddington reflects on Guardian about the phenomenon: “The couple (Libby Cope and Jacob Arnold) now have more butter than they know what to do with. Do they even know how much butter costs these days? Let them sell it!” Beddington jokes that this trend fits perfectly into … Read more

just completed a critical test before delivery

by

Spain is in a moment of weapons renewal. A few days ago we said that the country has been selling his old submarines for scrapa movement conditioned by something very specific: the new generation of S-80 submarines is beginning to gain traction. Or impulse, rather. And the ignition of engines S-82 Narciso Monturiol It is one more step towards delivery to the Navy. And it has cost… Milestone. It was last February 28 when S-82, the second submarine of the S-80 Plus series, started its diesel engines for the first time. The Ministry of Defense has become again echo of the achievement achieved a few weeks ago, and it is no wonder. The ignition is one more step in the commissioning of the submarine after the electrical ignition, the boarding of the batteries and the launching. Overcoming these phases brings the ship closer to its delivery. The S-82. The Narciso Monturiol measures about 80 meters in length, has about seven meters in diameter and is capable of moving about 3,000 tons while submerged. It has capacity for more than 30 crew members and can last submerged for three weeks. Regarding weapons, account with a system developed by Navantia and Lockheed Martin that allows launching ground attack missilesbeing the only of the European Union’s conventional submarines that have that capability. It can also arm DM2A4 heavy torpedoes with a range of up to 50 kilometers. Issues. And if the ignition of the engines is announced as a milestone, it is because the S-80 program has not had it easy. These are the first submarines of Spanish design, and since 2004 they have been suffering delays. The first in the class, the S-81 Isaac Peralshould have been delivered in the early 2010s, but design errors and a budget that went from 1.8 billion euros to 3,900, ended up being delivered in 2023. The biggest problem was weight, something crucial in a submarine. It had between 70 and 100 tons of overweightsomething that was discovered just when it was due to be delivered and that compromised the entire project because it is something that would cause buoyancy problems. There were also other problems in the propulsion system and disputes between the Spanish Navantia and the French Naval Group. Next steps. And, again, completing these tests is the step prior to delivery at some point this year. It also shows that there is someone doing the calculations somewhat regularly because the S-82 was scheduled to be delivered at the end of 2024, generating a delay in the plans. This delay is what caused the very veteran S-71 to have to be revised so that Spain could keep two submarines operational at the same time, giving itself the situation of having a new generation one alongside the aforementioned S-71. The next steps for the S-82 are to continue testing systems before delivery, and then the S-83 and S-84 will arrive, which were dated for 2026 and 2028 respectively and will arrive with a novelty: the BEST AIP system to improve immersion capability and long duration missions. Both the S-81 and S-82 will also be upgraded with the BEST AIP at some technical stop between 2029 and 3031, respectively. After that ignition of the S-82 engines, they start the most critical tests, such as those of acoustic signature and immersion, key steps before it can be launched into the sea to definitively retire the S-71.

Artemis 2 passes its life test and clears the path to the Moon

by

The mission Artemis IIwhich aims fly over the Moon againdid not have the best of luck in its rehearsals before launch due to the fuel and a hydrogen leak. But now NASA can breathe easy, since the second general test with fuel of the gigantic SLS rocket It has been a resounding success. and opens the way for humanity to return to the Moon half a century later. Without a doubt. Between February 19 and 20, 2026, engineers from the US space agency managed to complete the loading sequence of propellants without serious incidents, stopping the countdown exactly at the expected moment: T-29 seconds. The doubts about the engineering team are left behind and an imminent launch window opens that could start as early as March 6. Master hydrogen. Filling a 98-meter-high rocket with more than 2.6 million liters of superfrozen fuel is no easy task in practice. That is why in the previous test, carried out on February 3, we saw how it had to be aborted when the clock read T-5:15. And the culprit was none other than NASA’s old enemy: liquid hydrogen leaks. It must be taken into account here that liquid hydrogen is an exceptionally efficient propellant, but tremendously elusive, since it requires cryogenic temperatures of -253 °C. This extreme temperature causes the materials shrink in the rocketfacilitating escapes and increasing safety risks for the crew. Although this is what NASA found during the Artemis 1 mission in 2022. The repair. For this second attempt, NASA technicians meticulously replaced the defective seals and filters and the truth is that the move went perfectly. And during this last test, the filling was completed normally and the exhaust controls worked wonderfully. One step closer. The success of this trial is essential so that the Artemis program is not further delayed and neither is everything that will come after it. If we put ourselves in context, the Artemis mission was scheduled for September 2025, but was delayed until spring 2026 due to technical problems in the heat shield, batteries or control system of the Orion capsule. A big blot on paper that NASA needed to make up for with some success like this. When will it be released? In this way, the space agency already has its sights set on the launch window that opens from March 6 to 30the most optimal being to do it between March 6 and 11. That is why if everything follows the planned plan, the Orion capsule will be launched on a free return trajectory on a trip of approximately 10 days around the Moon, without landing on the moon. The objective. On board will be four pioneers who will take over the Apollo missions: Americans Reid Wiseman, Victor Glover and Christina Koch, along with Canadian Jeremy Hansen. Its mission is not only historic because it is the first manned flight of the program, but because it will serve to validate all life support systems before the main course: Artemis III. A project that has its sights set on carrying out the first manned landing on the south pole of the Moon since 1972 and, above all, overtaking competing countries such as, for example, China, which makes very significant progress in the space race.

There are people capable of testing positive in a breathalyzer test without having drunk a drop of alcohol. And we already know why

by

Although it may seem crazy, failing a breathalyzer test after drinking only water and a plate of pasta is possible. And while explaining it that way to a police officer may raise questions about a poor excuse, The truth is that it is a medical reality for those who suffer from the known self-fermentation syndrome. The investigation. Until now we attributed this problem to yeast, but a team of researchers from UC San Diego and Massachusetts General Hospital has identified specific strains of Escherichia coli and Klebsiella pneumoniae as those responsible for generate intoxicating levels of ethanol in the intestineopening the door to treatments as surprising as fecal transplantation. That is, there are bacteria that can literally make us drunk without drinking a drop of alcohol. The metabolic storm. To reach this conclusion, the study analyzed to 22 patients diagnosed with this metabolic problem, comparing them with 21 healthy relatives. In this case, the results were quite compelling, because fecal samples from patients in the midst of the outbreak were capable of endogenously producing ethanol at alarming levels. In order to know much more, These samples were cultured and an ethanol concentration of up to 136 mg/dl was observed.. To put it in context, in many countries the legal limit for driving around 50 mg/dl in bloodso these patients without drinking would be doubling the level of alcohol permitted while driving. An alcohol factory. The novelty of this study is that it shifts the focus from yeast to bacteria, since genomic analyzes showed a massive enrichment of genes related to mixed acid fermentation. But we must not fall for the statement that these bacteria are ‘bad’, but rather that the ecosystem is broken to give rise to this problem. And what is the trigger? The antibiotics. And the use of these drugs can sweep away the balanced flora, allowing opportunistic pathogens to take control of the intestine and begin to metabolize sugars into alcohol. The treatment. Logically, this is a serious problem, not because of the fact of testing positive in the alcohol test, but because of the toxicity that the body faces. That is why the objective right now is on the treatment that now has the focus on a fecal microbiota transplant. For this study, the donor of his fecal microbiota was a personal trainer with enviable intestinal health. And the result was incredible, since the patient with this problem saw these problems disappear permanently, and his ability to “self-produce” alcohol disappeared after repopulating his intestine with the healthy bacteria of another person. Beyond getting drunk. As we have said before, it may seem ideal to have a feeling of intoxication without having to spend a single euro on a drink, but the reality is that this problem also leads to non-alcoholic fatty liver disease. And constantly producing alcohol can cause very serious liver damage. But on the social issue, this endogenous overproduction of ethanol has led people to lose their driving license or face labor problems unfairly. All for a problem that may seem like the perfect excuse, but is actually a major medical problem.

OpenAI will start placing ads on ChatGPT. We already know who this first test will reach

by

For years, ChatGPT It has functioned as one of the most accessible gateways to artificial intelligence, an assistant that many people use daily without a subscription. That model, which helped popularize generative AI at a speed that is difficult to match from the end of 2022is now beginning to show its limits. Maintaining that promise of mass access has an increasing cost, and OpenAI has decided to explore an avenue that had been on the table for some time: will start testing ads in the chatbota movement that puts back on the table how the AI ​​we use every day is financed. ChatGPT is about to change. OpenAI says that ads will only be shown on the free and Go plans, while users of ProBusiness and Enterprise will be left out. The decision introduces a clear separation between plans aimed at the general public and those designed for professional or business use. As we can see, in this pilot, advertising is associated with the cheapest access levels, while higher subscriptions maintain an ad-free experience. This is what ChatGPT ads will look like Where the advertising will appear. There are also details on how advertising will be integrated into the user experience. In this first phase, ads will appear at the end of ChatGPT responses when there is a sponsored product or service related to the ongoing conversation, always separated from organic content and, as the company promises, clearly labeled. Therefore, we should be able to know why we are seeing that specific ad and we will have the option to hide it. What about conversations. Along with the announcement of this test, OpenAI wanted to establish in writing the principles that, according to the company, will guide its advertising approach. It insists that ads will not influence ChatGPT responses, which will continue to be optimized based on what is most useful to the user, and emphasizes that conversations will not be shared or sold to advertisers. It also promises control: we can disable personalization and delete data used for ads. For adult users only. Not all users or all conversations are included in this test. The firm points out that the ads will only be shown to adults who are logged in, and that both accounts in which the user indicates, or the system estimates, that he or she is under 18 years of age, as well as content linked to sensitive areas, will be excluded. Health, mental health and politics are among the topics prohibited from appearing in advertisements. Someone has to pay for AI. Generative AI has become an extremely expensive technology to operate, while, as is often the case with services with a massive free plan, converting those users into subscribers is not easy, even with cheaper paid plans. OpenAI earns revenue from subscriptions and its API for developers, and in that context testing ads fits as one of the ways the company puts on the table to expand revenue without closing access. The financial hole. The economic context is best understood by looking at the numbers published at the end of 2025. According to financial documents seen by The Wall Street JournalOpenAI assumes that it will continue to accumulate very high losses for several years before achieving significant profits towards the end of the decade. The projection for 2028 is even more demanding, with operating losses that would reach $74 billion, driven mainly by the cost of computing. The competition is getting fiercerz. Added to this financial pressure is a competitive context much more demanding than that of ChatGPT’s first months. OpenAI’s initial leadership is no longer as undisputed as in 2022 and 2023, with rivals such as Google with Gemini and Anthropic with Claude reinforcing its offer and gaining presence. Staying ahead requires constant investment, not only in research, but also in infrastructure and operational capacity. The announcement does not close the debate, it opens it. OpenAI insists that this is a limited test with no long-term commitments, but the simple fact of introducing advertising sets a precedent. It remains to be seen if this model is limited to the United States or if it ends up spreading to other markets, and how users react to this change. Ultimately, the question is broader and affects the entire industry: who pays the real cost of artificial intelligence that aspires to be in the hands of everyone.

It had been a long time since a cell phone left me speechless. So I went to China to test the Honor Magic8 Pro camera

by

If you asked someone from HONOR how they were going to improve the camera on their phones next year, the answer they would give you is that you hold the telephoto. A few weeks ago I was traveling to China to see first-hand the factory and the R&D laboratory from which the HONOR Magic8 Proa terminal that bets (almost) everything on the camera. And what a camera. Just stroll through the busy streets of Shenzhen or sit and enjoy the sunset in Hong Kong to discover that yes, HONOR has been working hard on its camera. I can’t talk about specifications, yet, but I can confirm that we have a wide angle, an angle and a periscopic zoom which is, without a doubt, the main protagonist. So much so that I ended up using it more than the main sensor for obvious reasons. That zoom was enjoyable A quality optical zoom not only makes the photo “look sharper”, but also gives a lot of play. The perspective we get with the telephoto cannot be achieved with a normal zoom (cropping of the sensor), since it is by using a longer focal length that we get that “compression effect” of the shots. Let’s say that the distance between two objects in different planes of the scene is reduced, something that is very useful in urban photography and allows us to achieve things like this. Photograph taken with the HONOR Magic8 Pro | Image: Xataka But let’s start at the beginning. Little can be said about the main sensor. It is a sensor that HONOR has clearly mastered and whose results speak for themselves. Good control of highlights and shadows, notable HDR work and faithful color representation, although some background work is noticeable to highlight the strongest colors. In this case, green. Photograph taken with the HONOR Magic8 Pro | Image: Xataka Photograph taken with the HONOR Magic8 Pro | Image: Xataka Photograph taken with the HONOR Magic8 Pro | Image: Xataka At night, the sensor knows how to surprise. It is no secret that there is a treatment for shadows and noise, but The result is one of the best I have seen to date.. These photos are really complex because you have fine details in highlights and huge contrast. The terminal resolves photos well, preserving detail, eliminating noise almost completely and keeping glare at bay. Photograph taken with the HONOR Magic8 Pro | Image: Xataka In this image we have to look not only at the enormous tubular building on the left, but also at its reflection in the next building. It is not a pastiche of lights without rhyme or reason, but the camera manages to perfectly capture the reflection without burning either the background or the building. Also notable is the definition not only of the lines of light, but of the light bulbs themselves hanging from the trees and the texts of the distant blocks. Photograph taken with the HONOR Magic8 Pro | Image: Xataka I liked it a lot during the day, but it’s at night when it really conquered me. If you told me 15 years ago that a gadget I carried in my pocket was going to allow me to take this photo, I probably wouldn’t have believed you. HONOR has done an excellent job not only in the camera, but in the processing. This image would be impossible to take freehand if there were not good stabilization, a good sensor and good background processing. Photograph taken with the HONOR Magic8 Pro | Image: Xataka But if this camera surprises, the telephoto is another story. The HONOR Magic8 Pro has a periscope with 3.7x optical magnification that we can digitally expand up to ten and 100x. The sweet spot, however, is x3.7. Because? Because we can get closer to the subject taking advantage of the full resolution of the sensor and take photos like these, I hope you are not hungry. Photograph taken with the HONOR Magic8 Pro | Image: Xataka Photograph taken with the HONOR Magic8 Pro | Image: Xataka In these photos you can perfectly see what I mentioned previously. Without an optical zoom we would not be able to achieve a blur as silky as this image. You don’t have to rely on portrait mode to crop your subject and blur the background, but you can achieve a superior effect by simply moving away from your subject and using the zoom. If you add a large, high-resolution sensor to that, you get a photo with exquisite textures. Photograph taken with the HONOR Magic8 Pro | Image: Xataka Photograph taken with the HONOR Magic8 Pro | Image: Xataka If we talk about urban photography, this periscope allows us to get closer to the scene and frame in ways that, normally, we could not achieve, either because it does not have a telephoto (something strange in the high range) or because the resolution of the sensor is not up to par. Photograph taken with the HONOR Magic8 Pro | Image: Xataka Photograph taken with the HONOR Magic8 Pro | Image: Xataka Photograph taken with the HONOR Magic8 Pro | Image: Xataka It also allows us to see things that we can only intuit with the naked eye. The advantage of having this resolution is that, even when cropping by zooming to 10x, we can achieve good results. Photograph taken with the HONOR Magic8 Pro | Image: Xataka Photograph taken with the HONOR Magic8 Pro | Image: Xataka The best thing is that the quality of the photos is preserved even when light is scarce. Normally, it is taking photos at night when I least enjoy testing a mobile phone. It is the most complex moment and where the seams are usually seen by the cameras. The HONOR Magic8 Pro is not exempt from those seams by any means, but the work that the Chinese firm has done is sensational.

We will have to wait to test the future with the Meta Ray-Ban Display outside the US: they are being victims of their own success

by

The Meta Ray-Ban Display are not perfect glasses nor do they pretend to be, but it’s hard not to feel that there is something different here. The idea of ​​having a color screen integrated into the lens, with speakers, microphones, cameras and even artificial intelligence, continues to sound more like a prototype than an everyday product. And yet, it is happening. Faced with other attempts to “kill” the smartphone that fell by the wayside, such as the AI Pinthese glasses aim for something more subtle. Screen on the lens, bracelet on the wrist. Beyond the concept, the Meta Ray-Ban Display is based on an unusual combination. The information appears on a small color screen located outside the axis of vision, designed for brief and non-continuous consultations. The control is not done by touching the glasses, but through the Meta Neural Banda bracelet that interprets muscle signals in the wrist area to execute minimal gestures. Meta presents this system as a more natural way to interact, reducing the need for buttons, touch surfaces or visible commands. Overwhelmed demand, expansion on pause. As explained this Tuesday by the companythe volume of interest has far exceeded the available inventory, to the point of generating waiting lists that extend well into 2026. Given this scenario, Meta has chosen to freeze the international deployment that it had planned in the short term and focus all its efforts on fulfilling orders already placed in the United States, while reviewing its availability strategy. This stoppage directly affects the plans communicated months ago. The company had indicated that the Ray-Ban Display would arrive in early 2026 in markets such as the United Kingdom, France, Italy and Canada, a first wave outside the United States that is now on hold. Meta does not speak of cancellation or set new dates, a prudent position that confirms the immediate stop, but does not clarify how long it will be extended. {“videoId”:”x9qouiu”,”autoplay”:false,”title”:”Ray-Ban Meta (Gen 2)”, “tag”:”Meta”, “duration”:”134″} Does the queue get longer here too? Although Spain was not in that first group of countries, the slowdown has obvious consequences for this side of the map. In launches of this type, expansion usually proceeds in waves, starting with the United States and continuing, in some cases, through key markets. In this case, Meta never confirmed plans for Spain, neither for this first generation nor for possible subsequent ones. The only thing that can be stated is that, if at some point these glasses end up reaching this market, the international delay makes it reasonable to think of an even longer wait. In Xataka Meta is so serious about smart glasses that its catalog is already a mess: this is how the new models differentiate themselves News for the Meta Ray-Ban Display. The stoppage in expansion has not prevented Meta from continuing to show progress. During CES, the company presented new functions designed to expand the uses of glasses, as a teleprompter mode to read prepared texts or possibility of writing messages by drawing letters with your finger on any surface, which are then transcribed into digital format. They are improvements that reinforce the idea of ​​a product in continuous evolution, even when its availability remains limited by supply and inventory.

Someone at Harvard suggested that 3I/ATLAS was an alien ship. A new test has revealed to us what it really is

by

Without a doubt one of the space objects that has been causing the most sensation in recent months is 3I/ATLAS. Practically everything has been said in recent months, from the fact that it is a simple asteroid that was going to destroy our planet to the fact that it was an alien shipas noted a professor from the prestigious Harvard. But all these ideas have been left in nothing thanks to the last signal that has been interpreted from this object. What he imagined. Interstellar object 3I/ATLAS, the third such visitor ever detected, has kept the scientific community (and science fiction fans) in suspense since its discovery in July. The most “far-fetched” speculations, as experts have described them, went so far as to suggest that it could be an extraterrestrial spacecraft, especially when it temporarily disappeared behind the Sun. The sign that explains everything. On October 24, the radio telescope MeerKAT In South Africa, a powerful network of 64 antennas captured the key evidence. This was neither an encrypted message nor a technological transmission from another species, but rather an absorption radio signal caused by hydroxyl molecules. What does it mean. Hydroxyl molecules are the direct result of the ‘breaking’ of a water molecule. This is something that happens when the ice in the nucleus of a comet approaches the Sun and sublimates due to the large amount of energy it absorbs. That is, it automatically goes from solid to gas and this is what we have detected from Earth, as has explained Michael Küppers, scientist at the European Space Agency (ESA). In summary, we are talking about 3I/ATLAS containing ice inside, as happens in comets (and not in extraterrestrial spacecraft). And we are completely sure of this, since these absorption signals are like the molecular DNI, it is unique for each compound. Goodbye speculation. As we have mentioned before, the alien ship theory gained traction when the object hid behind the Sun. Some speculated that it was maneuvering or hiding from our radars. However, on November 4, 3I/ATLAS reappeared exactly where orbital calculations predicted it would be. There were no maneuvers, just physics. Furthermore, it is not the first time it has been detected. Javier Peralta, an expert in planetary atmospheres, recalls that NASA’s Swift space telescope had already observed hydroxyl in the ultraviolet spectrum. MeerKAT’s new detection is crucial because it confirms the same composition in a completely different band of the electromagnetic spectrum: radio. What does the future hold for us? 3I/ATLAS is the third known interstellar visitor, after 1I/’Oumuamua in 2017 and 2I/Borisov in 2019. Although its trajectory is too long and it has traveled too long to know which star it comes from. But the important thing is that we are already preparing for what is coming. ESA’s JUICE mission, currently en route to Jupiter, will take new radio measurements from 3I/ATLAS in February 2026. But the big bet is the mission ESA Comet Interceptorwhich will be launched around 2029 and will wait for the next large comet to approach our planet.

Waymo lands in the great litmus test of its cars

by

Hello, London! With a simple and straightforward message, Waymo has confirmed that next year it wants to operate its driverless robotaxis in the city of London. For now, the company has to work with the authorities to win their favor if it wants to have full availability next year. It is a litmus test for fully autonomous driving in Europe. What is already known. Although it has been reported in numerous media outlets that Waymo will offer driverless trips next year, the truth is that this is not entirely the case. What Waymo has announced It is their intention to be able to offer this service but first they have to gain the trust of the regulators. For now, the company that was born from a spin-off of Google’s autonomous car will begin to operate with a human behind the wheel in specific spaces within the city. Once you obtain approval from the authorities, you will be able to offer this service to citizens. Why London? Waymo’s choice of London is no coincidence. It is not even the only company that aspires to put fully autonomous cars on the streets in the English city. Uber and Lyft They also have their own plans. If London ends up giving the go-ahead to any of these companies, it will be the first city in Europe to allow this service. The announcements have been coming in cascade since last June It will be confirmed that the United Kingdom aspires to allow these services from the spring of 2026. The British Department of Transport has advanced the deadlines by one year and they hope that in 2027 the services can be active throughout the country. A trial by fire. Although up to three companies have already shown their intention to put their cars on the street, what we will see in London will be the confirmation of whether the technology is mature enough so that cars circulate correctly in European cities. London, like many European cities, did not plan the center of its cities that date back to the Middle Ages. The network of narrow streets, complex intersections, roundabouts and a greater number of pedestrians is a challenge for robotaxis that must be able to process an almost unimaginable number of variables in real time. And the variety of scenarios and dangers that any car faces in the center of European cities has been presented as the main obstacle for companies that intend to put their robotaxis on the streets but also for companies like Tesla that aspire to have its most advanced autonomous driving systems. With leaden feet. Although the United Kingdom has its own plans, the truth is that Europe has been cautious in the field of autonomous driving. At the moment, only Mercedes has permission to circulate without the driver paying attention to what is in front of them. Of course, on previously mapped roads, with good lighting and a maximum of 60 km/h. That is to say, the system is as expensive as it is slow. The other actor that leads the way is Ford. The North American company has permission for its drivers circulate without hands in the United Kingdom and over thousands of kilometers within the European Union. Of course, the roads must be previously mapped and the driver must be able to take control immediately if the situation requires it. Companies, however, have been pressing for some time for Europe to expedite a regulation that never seems to come. The most active has been Tesla, which has published videos showing cars with the Full Self Driving activated to circulate completely autonomously in spaces as complicated as Rome either Paris. The security. The big problem that companies face is security. Waymo claims that its cars are 78% less likely to suffer an accident with injuries than a human. And the website where they announce their intentions in London it is a continuous reference to its security systems. The great obstacle for companies is to convince that this is true because when a vehicle of this type plays a leading role in an accident with fatalities, it generates more distrust than if the vehicle is driven by a human being. It must be taken into account that the autonomous car has to coexist with the decisions of other human beings, so the consequences, in part, of an accident may escape their control. To this we must add that the vehicle must understand without errors what it should do at all times. This can be a significant obstacle when a computer failure occurs, a loss of connection or, simply, a new situation that had never been contemplated. In San Francisco, for example, Cruise cars have been accused of hinder emergency services. What’s at stake? According to the most optimistic perspectives, a business close to 600 billion dollars in less than a decade for driving. autonomous (including the possible services that manufacturers incorporate to their individual clients. It is the great hope for companies that have already burned tens of billions of dollars. Obviously, the business is in a drastic reduction in operational costs which puts human drivers at risk. For now, in Guardian They report that taxi drivers have received the news with skepticism, pointing out that Waymo’s service in the United States is more like a tourist attraction than just another mobility alternative.
