We have genetically edited a spider to produce a fluorescent red cloth. And the implications are promising

by

Mutant spiders. It could be the premise of a film that mixes science fiction and terror, or someone’s nightmare with Arachnophobia. However, the first mutant spiders created by the human being respond to something much more innocent. But maybe even more interesting. Mutant spiders. A group of researchers He has genetically edited A group of spiders. The most curious of the results obtained by this team is probably a group of spiders that, after the edition, are capable of weaving a red spider web fluorescent spider. It is about First experiment of genetic edition in spiders of which we have knowledge. For this, the team resorted to specimens of the American domestic spider (PARASTIDA TEPIDARIORUM), A species that, like many others, uses its spider web not only for hunting but also to protect its eggs. A fascinating material. Spider silk is one of the most interesting materials in the animal world. Spiders are capable of segregating different types of fabric and among them, structural silks are among the most remarkable for their very tangled resistance that binds to its elasticity, lightness and the fact that it is a biodegradable material, explains the team responsible for the study. CRISPR-CAS9. In its experiment, the team turned to the “scissors” of genetic edition CRISPR-CAS9. They began the process focusing on a gene linked to the development of the eyes with the aim of obtaining a first easy result to identify. The team injected his tool of genetic edition in a female in order to eliminate the gene chosen in their reproductive cells and thus be able to detect changes in their litter. The Resutlanted: Spiders who did not develop their eyes. From the eyes to the silk. The first success led to repeat the test, but this time focusing on the genes responsible for coding some of the proteins present in the structural silk of the spiders. In doing so, spiders wove spider silk filaments of fluorescent red spider. The details of the experiment were published In an article In the magazine ANGEWANDTE CHEMIE. A first step. To be able to edit the genes responsible for the production of a material as interesting as the structural filaments of spider fabrics opens new doors when it comes to knowing this material and its biochemical origins. Of course, we can also pave the way for being able to synthesize it efficiently or even in the development of materials with similar properties. “We have demonstrated, for the first time in the world, that (the tool) CRISPR-CAS9 can be used” to incorporate a desired sequence in spider silk proteins, thus allowing the functionalization of these silk fibers, ” stood out in a press release Thomas Scheibel, co -author of the study. “The ability to apply CRISPR genetic edition to spider silk is very promising for material science; for example, it can be used to increase the already high spider silk breakage.” In Xataka | ‘The Last of Us’ is already happening in the animal world and the last species in suffering are the “spiders of the caverns” Image | Patrick Edwin Moran / University of Bayreuth

Four AI companies control how Half Mundo reasons. It is the greatest concentration of intellectual power in history

by

While the public focus is concentrated in the possibility that the AI ​​will take our job ahead (Business Insider 21% of its template has just announced citing it as a cause, the CEO of Axios has published A text by the chungosAnthropic’s CEO has shouted “that comes the wolf” to justify that only they can save us), In the background something less visible is happening: We are giving our intellectual autonomy in favor of efficiency and comfort. It is not just that four companies –Openai, Google, Anthropic, Meta – are building the infrastructure with which millions of people resolve doubts and make decisions. They not only manage data: they also protect the way we link ideas. The Great Chinese of AI They are out of this equation for a simple reason: their still domestic approach without the international vocation of the Americans. Google (the search engine) was and is influential, but with it we have had to spin our own speech: Cotejar Fuentes, Weighing biases, assume contradictions. The generative AI instead serves a round response that It sounds coherent even when hallucin And that’s why he demands less surveillance. The result is that we are replacing the “internal process” with an external verdict covered with a technological aura that deter the replica. Whatever you say, Chatty. Delegate is too tempting. Save time and headaches. The problem is that we do not subcontract logistics, but criteria. We ask Chatgpt A professional strategy. TO Claude A curriculum. TO Gemini today’s interpretations. In doing so we accept without discussing the biases and empty of a trained model about texts that we will never see. It is an invisible assignment and, therefore, difficult to question. Never before so few hands had defined what questions can be asked and what answers sound reasonable. History has known infrastructure monopolies – electrity, internet, railways – but never one about reasoning patterns. Now another qualitatively appears: It operates on the symbolic plane, where narrative frames are defined through which we understand the world. Very subtle and very decisive. What previously implied a deliberation – read, contrast, imagine scenarios, weigh nuances – today becomes an instantaneous response, of definitive appearance. What to think about euthanasia? How to react to infidelity? What economic model is more fair? We no longer look for elements to think: we look for the correct answer The faster and more comfortable. And we accept as valid the one that sounds best, even if it ignores what does not fit in your narrative. Its effects will not be immediate, but predictable: a slow loss of variety in thought, of ideas out of the ordinary. Platforms have progressive consequences. Tiktok and Spotify, for example, They have made the songs last less and the chorus arrive before. What consequences will the LLMS within fifteen years? If we all consult models that converge towards average responses, intellectual eccentricity – culture rate for innovation – It will be increasingly weird. There is hardly a brake for AI, but perhaps at some point we have to decide how much reasoning we are willing to deliver before staying without it.

There are those who are adding fungi such as cordyceps to coffee to lose weight. Science has many reservations

by

Coffee is a food, with numerous positive effects on our body. We get more and more about this Positive coffee actionbut we have determined to improve it adding supplements as proteins either Spirulina. One of the latest trends? Enrich coffee with fungi. So that? To lose weight. And here the evidence is not so clear that this trend of ‘Mushroom Coffee’ is so healthy that invites a coffee with cordyceps to drink. The promise. Eating mushrooms or fungi has nothing weird, but a few years ago we began to see how the food industry It began to add them to other foods to create improved versions of them. One of the first brands that added fungi to the cocoa or coffee was FOUR SIGMICan American company that creates “functional foods” and well -being supplements. That is, coffee is not only coffee: it has a series of additions vegetables to relieve these, support the immune system or accelerate weight loss. The latter is what a more recent grabs Trend in networks like Tiktokthe baptized as ‘Mushroom Coffee’. There are several brands that sell coffee with fungi Cordyceps coffee. The defenders claim that coffee (and other foods) can be enhanced with medicinal fungi whose compounds carry a series of positive effects. Among those fungi are Reishithe León hairhe Maitake or the Shiitake (great in broths)but also the most famous cordyceps. Yes, that parasitic fungus that makes Some ants become ‘zombies‘And what is protagonist of the Apocalypse of ‘The Last of Us’. These fungi can increase energy production and improve metabolic function, helping in the burning of fats. They can also help control hunger, stabilize glucose levels and have Probiotic properties that favor both digestion and nutrient absorption. Market. And it is not a bizarre or the US thing: you can Buy coffee With cordyceps In Amazon If you want the healthy effects of coffee more, Chow they announcegreater energy and improvement in your mental clarity. There are different estimates, but this coffee market is expected to grow at a rate of between 5.4% and 5.7% during the next decade. There are studies that place their value at 1,203.4 million dollars in 2023 with a growth up to 1,833.4 million by 2031. They are considerable figures, but we compare, the estimate of specialty coffee is 62,500 million by 2032 and that of the entire market It will be of 632,000 million for that year. But well, it seems that this trend, little by little, is consolidated and grows. The small print. The logic here seems simple. In the case of protein: if it is a good supplement and coffee is a good food, mixing them works. With fungi and coffee the same thing happens, but something that should not be overlooked: there is a lack of research. The relationship between coffee and weight loss is well documented, being a good stimulating before performing some training and selling the caffeine as supplement. But, although the properties of these fungi are also documented, evidence on coffee with fungi and its action in weight loss or mental well -being is limited. Clinical trials are missing that confirm its direct effectiveness to lose weight and most of those available studies are in animals. Also, as we read in VogueNutritionist Marta Marcè comments that it is not usually specified whether the extract is from the fruiting body (rich in properties) or the roots (less powerful), in addition to using very low doses. And sometimes It is not even the real fungus. Dangers. Although cordyceps has a bad reputation due to fiction products in which it has been the protagonist and its effect on some insectsusually has no health hazards. Cordyceps coffee is approved by the USDA -The United States Department of Agriculture-, but you have to take some things into account. It may produce some allergies in certain people and it is necessary Influence when combining it With other stimulating products or drugs, but most importantly, above all, it is to know where those fungi that supplement chocolate or cocoa. Marketing, already such Because here the danger is how that fungus has been manipulated and the example we have had in Colombia, where a health alert on cordyceps supplements not regulated or fraudulent. And if you dare to try it, be from reliable and out of curiosity, not so much for its numerous promises, that millions move in the other part of the world.

The burning is one of the most mysterious sites in Mexico. And their fire craters continue to baffle archaeologists

by

Mexico is a archaeological treasure And, although the Yucatan Peninsula be the one that usually monopolizes All eyes due to Mayan ruins and initiatives such as Mayan train for enhance tourismthe central area of Mesoamerica It is home to other relevant archaeological sites. One is the burned one, which is said to be the original place of The Aztecsand, although there are several mysteries associated with the place, a study He has focused on analyzing the enigmatic fire pits. It is not known if it is where the Mexicans were born, but they have discovered when they lit and ventured to decipher for what they served. Chicomóztoc. Located in a privileged central area of ​​Mexico, it seems clear that, due to its location, natural resources were abundant, being able to be a strategic area for nomadic peoples to supply. At some point in 300 AD A town settled in the placewhere what would later know as “the burned one” was founded. The site reached its peak towards the 800 AD, when it began to fortify strongly to compete against nearby locations, and took place until 1200 AD It is estimated that it was then when a progressive abandonment and, When the Spaniards arrivedthey found ruins with numerous fire traces. Legend has it that, because of this, they baptized the site as “The burned”And it was Francisco Javier Clavijeroin 1780, who associated the site with the mythological original place of the Mexica: Chicomóztoc. Part of the citadel and pyramid The patio of columns Archaeological zone. Located on a hill, the burned one has numerous architectural remains. Using mortar, stone and vegetable fiber, its inhabitants built a series of buildings whose purpose does not differ from that of many others Archaeological sites from Mexico. Thus, we have defensive structures such as a wall of four meters wide and up to six high, or one 70 -meter long ball courtbeing of the Longer Mexico. Also ceremonial buildingslike the votive pyramid About 12 meters high, the Hall of Columns or an Observatory that would serve to monitor and that could also have had astronomical functions. The function of the different elements is more or less clear, but there is something that has confined archaeologists for a long time: huge holes. The holes. The inhabitants of the burned were built in phases about the old structures, but something that stands out is that the recent analysis performed by archaeologists points out that the holes were used at all times. There are several, but they focused on five of them called from LQ1 to LQ5 and, through the Archeomagnetism techniqueThey have been able to identify when they were active. This technique is like reading a fossil compass that allows you to know how many years a clay or stone material has been very heated. When this occurs, internal minerals are oriented according to the Earth’s magnetic field At that time, being “recorded” the orientation forever. It is something that allows the rocks to be dated and find out when it was the last time that element was heated. Thus, they identified that the LQ4 and LQ5 holes were used in the apogee era, between 675 AD and 903 of the LQ1 was lit between 927 AD and 1101 AD and the LQ2 showed more confusing data, but they estimate that it can be the oldest. And from LQ3 no data were obtained. Mystery. Several theories have been established on their use, some pointing to harvesting ceremoniesothers linked to change of stations and also those that suggest that they were torches for night ceremonies. This mystery will be difficult to solve, but as we read in The green compassLQ1 is the one that has caught the attention of researchers. “Its date coincides with the collapse of the site, so perhaps the rituals persisted until the end, as a symbolic farewell,” they say. In addition, it is the closest to the votive pyramid. The different dates of use of the holes, however, reinforce that theory that abandonment was gradual and that, even in the last moments, “the fire could be a way to keep the memory of the place alive.” As we say, it will be difficult to clarify What kind of ceremonies were celebrated In them, but the next step of the project is to study the rest of holes that have not yet been excavated.

We have been creating whale bones to tools for a long time. Before even learning to hunt them

by

For centuries, whale hunting was a weight sector in the coastal areas of the Gulf of Bizkaia. Everything took advantage of this animal, or almost everything: the meat served as food and fat served as oil to enliven the flames of the lamps before electricity and oil. His bones have also been A valuable resource Throughout history. Now we know that also during prehistory. Prehistoric tools. A group of researchers, including scientists from the Institute of Environmental Science and Technology of the Autonomous University of Barcelona, He has discovered Tools made of whale bone. The analysis of De Ha throws an estimated age of between 19,000 and 20,000 years. The 83 tools were found In various deposits Distributed by the coast of the Gulf of Bizkaia, including the Cantabrian coast and points in southern France. To these tools you have to add another 90 unrelated bones found in the Cave of Santa Catalina, Located in the Biscay town of Lekeitio. The bone remains would have belonged to specimens of at least five different species, including species such as the sperm whale, the common whale and the blue whale that can still be found in the waters of the Gulf and the gray whale, already disappeared from that environment with a more restricted habitat to areas of the northern Pacific and the Arctic Oceans, explains the team Investigating what and when. For the identification of the species and dating the tools, the equipment resorted to the mass spectrometry techniques and radiocarbon dating. Thus they managed to find the origin of the tools in the five species mentioned above. It was also like the team determined that it was, In words of the Jean-Marc Pétillon group “some of the oldest known evidences of human use of whale remains as tools.” “Zooms is a very powerful technique to investigate the past diversity of marine mammals, especially when there are missing diagnostic morphometric elements in bone remains and objects, something common in artifacts made of bones,” explained in a press release Krista McGrath, co -author of the study. Chemical analysis. The study also involved a chemical analysis of the sample. Thanks to this, the team was able to find out data on the eating habits of the whales, which “differed slightly from those of their modern counterparts.” This implies possible changes in the behavior of cetaceans, or in the marine ecosystem itself. The details of the study were published In an article In the magazine Nature Communications. 20,000 years hunting whales? The conclusion that the human being has 20 millennia hunting whales is tempting, but the team responsible for the study considers it “extremely unlikely.” The most likely hypothesis is that the Pleistocene hunters would have taken advantage of the arrival of stranded whales to the coast to obtain their bones and manufacture from them “It is extremely unlikely that these species would have been accessible to the hunters collecting European pelistocene in another way that were not through passive acquisition methods, such as the opportunistic acquisition of stranded whales or the arrival on the coast of corpses,” says the article. “There is no evidence (…) that the collection hunters of the European Pleistocene had the necessary technologies to hunt these species, such as navigation (…).” Change of sea level. Study coastal life in glacial ages since the present coastline is relatively Far from the coastline typical of the last glaciation, although the extension of the lands flooded after the end of the last glacial era differs between area and area. Within the Gulf of Bizkaia, for example, we can appreciate a greater area flooded on the French coast and therefore a greater decline of the coastal line in contrast to the Cantabrian coast. In any case, the coastal recession implies the loss of valuable coastal deposits now flooded by the Atlantic waters. Deposits that could hide countless data that could help us to know better these life modes of the millennium coastal peoples behind in time.

North Korea was going to throw his greatest war boat and ended up sinking it into the sea. Everything points to a culprit: Kim Jong-un

by

Making a fool of it is something that It is not anyone’s pleasure. Surely you have ever stumbled down the street and looked around to see if someone had seen you. Now, imagine that what stumbles is a Military ship of 5,000 tons and several million dollars and sinks at the time of its premiere. That is what happened last week when Kim Jong-un He witnessed how His brand new war ship sank before the impotence of all those present and under the watchful eye of the rest of the planet. And everything indicates that the error was because, as the Spanish proverb points, the hurry are not good. Short. Days before the event, satellite images They showed both the vessel and a scenario in which what seemed to be an observation zone. Probably, the place from which Kim Jong-un was going to witness that historic moment. And the truth is that it was historic, but not for the reasons he would have wanted. On May 23, during the launch ceremony of the new North Korean destroyer (the second of its most advanced class), all attendees in the front row and the world was witnesses of a Technical failure that ended in disaster: the ship overturned. That symbol of power, with 143 meters in length and 74 vertical missile launch cells, ended up ridiculous. How do we float it? Satellite images later Analyzed by the Center for Strategic and International Studies, or CSIS, they showed the ship partially sunken with tarps that covered the disaster. And, although at first the rush was blamed, we now have more clues about everything that could go wrong. Obviously, there is no official information from North Korea, but in The New York Timeswe can see that there are analysts who are quite clear what the problem was. Or the sum of them. Image | CSIS/BEYOND PARALLEL/MAXAR When a ship is finished, there is Several ways to ‘throw it’ into the water. We have the sliding launch in which the ship slides on a ramp into the water. The dry dock in which the ship is built in a dry dock and, once finished, the water dike is filled (That is done with cruises). Also the mechanical launch by cranes, the launch with airbags that are placed under the ship and allow it to slide to the water. And the side launch that drops the side ship into the water. Normally, a single technique is used, but in the North Korean destroyer disaster it seems that sliding and side techniques were used. And not because that’s how it was planned. Perfect storm. As noted The New York TimesIt was the first time that analysts watched North Korea use the side launch to throw a war ship. This technique is sure if it is done well, but in Large ships It is more likely that a problem appears, with dire consequences if it happens. The reading of the analysts is that, using that technique for a 5,000-ton ship points to a lack of experience added to the political pressures by Kim Jong-un to achieve rapid results. The destroyer was manufactured in the port city of Chongjin that has experience assembling ships of such magnitude, but not something as huge as this ship. This puts on the table that a possible trigger was that inexperience When throwing such large ships. In the absence of a dry dike of the appropriate size, it is estimated that the engineers tried the lateral launch to throw it into the water, but the angle was not correct and, when trying to slide it, the ship was unbalanced and ended up lying on the right side. When it goes well, as happened with this fighting ship of 3,500 tons in 2013, it is worth seeing: And it can also go wrong: The hurry are not good. Interestingly, this destroyer is from Choe Hyun classwhose first model was inaugurated successfully Last month. It was going to be the second great frigate of North Korea and the new example of that naval remodeling that Kim Jong-un is promoting. And the precedents were good: the first It was built In the city of Nampo and, because it is a larger shipyard, they could put it afloat through the technique of dry dock. There were no major problems and, at the inauguration, the ruler saw how test missiles were thrown successfully. However, there are hurry in the government dome to follow demonstrating to the world its military potentialwhich has led the president to visit the shipyards who are building new ships to accelerate delivery deadlines. In addition, there are information They point out that, although the ship could have thrown out correctly, the ocean exit street is narrow and has a questionable depth. I made a. pic.twitter.com/urflog6leo – Dr. Jeffrey Lewis (@armsControlwonk) May 22, 2025 Firm hand. And who will pay for this? At the moment, the ridiculous has resulted in several arrests of members of the responsible shipyard itself. The Central News Agency of Korea reported that the chief engineer, a senior armament official and another member of the installation had been arrested, and Kim himself described The accident as a “criminal act”, demanding An urgent restoration of the ship before June. Country engineers estimate that, pumping seawater, they can straighten the ship and repair damage. And it will take about ten days to do it, but it seems complicated because, after a week, Keep as it was. Sentinel-2 images of May 23 and 28. Despite the clouds, we can see that the destroyer continues exactly at the same point And sarcasm. From South Korea, which always have an eye and a half placed in what their neighbors doThey think something else. Yang UK is an expert in North Korean military affairs of the Asan Institute for Policy Studies in Seoul and, as Tnyt comments, the incident may not be only an accident, but something caused by a structural imbalance on the ship itself. … Read more

A group of scientists has proposed to infect another world and see what happens as an experiment. His candidate: The Enced Moon

by

While NASA’s rovers are still looking for clues on Mars, Jupiter, and Esturno, Saturn’s icy moons, of Jupiter, of Jupiter, They have become the main candidates to house microbial life outside the earth in the solar system. But what will we do if we discover that they are not inhabited? A controversial idea. Encard, with Your subsurface ocean and confirmed presence of crucial elements for lifeIt is a usual focus of scientific fascination. The European Space Agency Plan to send a probe there which would arrive in 2054. Anticipating a disappointment, a group of astrobiologists has launched a bold proposal: if it turns out to be uninhabited, we can consider “infecting it” deliberately with terrestrial microbes to observe how life spreads in a habitable but virgin world. An unprecedented experiment. Since they began to explore the solar system, large space agencies have taken very seriously not to contaminate other planets and satellites, building their probes in clean rooms to reduce the number of bacteria that could survive on board. This experiment would be to do the opposite. It would be the first planetary scale attempt to build a biosphere. It would force us to learn how to assemble complex ecosystems from scratch, which organisms are the most appropriate to do so and how they behave in extraterrestrial conditions. Why sow life in another world. Charles S. Cockell, Holley Conte and M. Dale detail their idea in an article published By Space Policy magazine. The group argues that, if future missions confirmed the absence of native life in Encela, the deliberate inoculation of the satellite would help us understand how life spreads in permanently dark oceans. Inoculation would allow to investigate how bacteria ecosystems were organized On the ground snowball or even If hydrothermal chimneys From a primitive land they could be the place where life arose on our planet during the early or early archaic times. A multiphendary economy. Entering a more speculative field, an inhabited brain could, in theory, become a source of materials for the exploration of the exterior system if humanity would become a multiparaneary species. The authors even mention the engineering of organisms as an option to make the new biosphere, transforming the ocean of the Saturn moon into a “biofuel production plant”, once our metanogenic bacteria have prospered. It could even resort to synthetic biology to design optimized organisms. Faster than terraft Mars. The experiment would, of course, a multigenerational company, but unlike Mars the terraftwhich would take centuries, the inoculation of an extraterrestrial ocean could be achieved with current technology and would be “much simpler and less expensive.” But there are also ethical implications. How many missions are needed to be sure that it is really uninhabited? Is such an experiment more valuable than studying the geological and geochemical processes of a virgin world? And perhaps it is also possible to ask: will we be able to guard a second biosphere, in addition to that of the earth, for multiple generations? It is worth thinking in the long term, but we must previously intensify our sense of responsibility for the Earth’s biosphere.

In the fierce war for augmented reality, China has five “dragons” willing to win it

by

I’ve been observing from the barrier how the career of The augmented reality. And, I must be Franco: so far no one had taken it seriously, not even Apple. Vision Pro It is a brilliant product, but niche. Very niche. Google herself renocated in her most important event of the year, the I/or 2025 which believes to recognize as a key to democratize access to this product category. “We know that glasses can only be really useful if you want to wear them all day.” And Android XR arrived Android XR marks a before and after. It is the first real effort to create an accessible mass platform for every manufacturer that bets on augmented or mixed reality glasses. What seemed An initial project in conjunction with Samsung To develop a VR helmet, it has ended up materializing in a paradisiacal garden on which any manufacturer can walk. This operating system will play a fundamental role in the popularization of A format with great sale potential: Traditional glasses with augmented reality. A platform through which users can use (naturally) apps such as Google Maps, photos and, the most important, Gemini, on reduced size devices. Google is not winning only the race when developing an open platform that gives life to a product that free us (at least partially) of the smartphone, is also leading Who offers the best assistant driven by AI. The Gemini native integration In augmented reality glasses it makes even more sense than a mobile. The voice command becomes almost an essential when the physical interaction with the device is minimized. It is, in fact, Google’s goal. Free ourselves from the smartphone in daily tasks How to call, follow addresses towards some point or something as simple as adding a reminder to the calendar. The friction is minimized to remove the mobile from the pocket for any of these purposes. Glasses, voice command, effective execution. THE BATTLE FOR PRICE AND FORMAT Vision Pro or even Quest target are born as niche products. Apple sells mixed reality at almost 4,000 dollars (taxes included), with results below analysts’ predictions. About 175,000 units sold in a year. Goal has been Selling the Oculus Quest as hot breadwith an accumulated of 20 million units. Perhaps the quality-price has something to do. So much that Apple considers to focus efforts on more economical vision. “We know that glasses can only be really useful if you wanttake them all day. “ Virtual reality has its niche, But the augmented opens to products mainstream (glasses that you can wear almost all day), a formula that starts working. Not satisfied with Meta Quest figures, the company started four years ago an incursion into the world of traditional format glasses next to Ray-Ban. First with Ray-Ban Storiesand Three years later with Ray-Ban Meta. A new product, a “new” format, and One million sales in their first year of life. The “traditional glasses with headphones and things” works. But the goal is missing a platform adapted to this format and less limited hardware (these glasses can barely record some video, receive notifications and call). And there China comes into play China has been engaged in a career to lead the technologies necessary to create traditional format glasses with augmented reality. And there are five big names in it: XREAL Rayneo Rokid Immobile Meizu It is curious how, beyond giants like Huawei (whose platform Harmonyos does not currently prioritize AR devices) innovation in this territory is in the hands of small businesses. XREAL It is a start-up that already works in some Badge glasses Under the Android XR platform. It will be a product to take into account and relevant to China, since Most hardware is produced nationwide (currently 65%, with the aim of reaching 100% on a two -year horizon). Instead of betting on Qualcomm technologies, Xreal has its own chip for glasses, the X1. Rayneo It may sound more, and it is a subsidiary of the Chinese giant TCL. He is working with Alibaba to take AI models to smart glasses and, for the 2028 Olympic Games, they plan collaborate with COI to create promotional videos in which the perspective of athletes (which will wear scratch glasses) is the protagonist. A look at your website It lets us see that they are focused on markets beyond the Chinese, with the focus currently on the projection of content. Rokid It is founded by an ex-alibaba, and manufactures glasses that use the QWAN model (precisely Alibaba) to translate into real time. It has enough state support, and works with national companies. Although it has a consumer product, it is quite focused on specific solutions. Immobile He is one of China Mobile’s main collaborators in his attempt to develop one of the great national language models. Jiutian LLMone of the first models, and is being tested in the glasses of augmented reality of immobile. Their abilities are multimodal (voice, text, compression of what you are seeing), and the connection is direct by 5G to the cloud of China Mobile, without the mobile as an intermediary. Finally we have Meizua historic Chinese manufacturer who tried in Spain with its mobiles but could not with Huawei and Xiaomi. The company has developed Llm Flyme a multimodal AI engine that vertebra both its XR devices and its connected car systems. They also combine text, voice and visual recognition, integrated in recent launch glasses, such as their Starv Air 2. A company recently acquired by the Geely engine giant, with expansion plans outside China. The keys to winning this format race Although Google has put the platform on the table and has set your hand to companies that want to collaborate with it, this It is still a war to dispute And in which there are still no proposals for attack to the generalist public, beyond the first goal approach with Rayban … with glasses that do not even execute augmented reality. Google has important strategic advantages: its Android ecosystem is unbeatable … Read more

Its technology aims to reduce the scope of the enemy sound

by

In the underwater world, noise can be a sentence. The more silent a submersible, the lower the probability that it is detected by sounding. Although artificial intelligence begins to change the rules of the gameefforts to further reduce the acoustic firm do not cease. As SCMP points outthe last advance arrives from China, where a team of researchers has developed a technology that, in laboratory conditions, has managed to significantly cut the vibration that is transmitted from the engine to the helmet. The idea starts from replacing the traditional engine rigid supports with a hybrid structure of active-peasive insulation. The system was presented at A study reviewed by pairs published in Noise and vibration control By researchers from Jiao Tong University in Shanghai, in collaboration with China State Shipbuilding Corporation (CSSC). According to the authors themselves, a reduction of only 10 decibels at the noise level of a underwater vehicle could decrease its 32%detection range. A double control system. The system combines two elements. On the one hand, a steel-gum-steel ring that acts as a passive shock absorber. On the other, a series of 12 piezoelectric actuators that surround the engine and neutralize micromovimientos with the help of precision levers. These actuators are designed to adapt to reduced assembly space. The combination allows to reduce both structural vibrations and low frequency sounds, the most problematic for stealth. The system is governed by an FX-LMS algorithm, an adaptive method that coordinates the 12 actuators and avoids interference between them. Thanks to this intelligent management, the system can adjust your response in real time, which allows you to maintain control even in the face of unexpected variations in engine behavior. The method is based on rebuilding the interfering signal to feed the noise cancellation. Promising results, but in laboratory. The tests were performed with a 200 kg simulated engine mounted on a cylindrical metal housing. The system was designed to operate with a regime of 1,500 revolutions per minute (25 Hz). At 100 Hz, the passive system managed to reduce noise by 12 dB. With the complete system, the attenuation reached 24 dB. At 400 Hz, the reduction was 26 dB. The researchers explain that the chosen frequencies correspond to the most common spectral lines of the engine. A development still with questions. The study also indicates limitations. The rigidity of the rubber used in the passive system can be affected by temperature and pressure variations, and the durability of piezoelectric actuators has not yet been verified in real operating conditions. In addition, researchers do not specify what type of underwater would use this technology or the final impact that it would have on its global acoustic profile. In fact, the term “underwater vehicle” is used throughout the study. That is, they do not speak of diesel-electrical submarines or nuclear submarines. For now, it is an experimental development with promising results. The participation of CSSC suggests strategic interest, but there is no confirmation that this system has been integrated into any operational platform. What demonstrates is that China continues to bet on advanced technologies to reinforce its underwater stealth, an important factor in the modern naval war.
