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.

There are no diesel motorcycles for a very long list of reasons. This American brand doesn’t care about a single of them

by

Motorcycles are not gasoline by whim. They are because diesel engines are unfeasible For the very nature of the behavior of a motorcycle, although there are those who have determined to resurrect a concept that, every time it has tried, has not managed to go beyond the anecdote. Why my motorcycle is gasoline. There is a very long list for motorcycles to bet on gasoline and not by diesel: the first is that they are designed to have a relatively content size and weight that allows them to be driven. Diesel engines are heavier that gasoline engines due to their compression ratio (burn with much more pressure and inevitably need more resistant and heavy materials). They also work in a very low range of revolutions, ideal to minimize consumption, but with much less response for a vehicle born to be agile and sportsto a greater or lesser extent. An industry that seeks to be profitable. They are also more complex to manufacture and maintainan especially important cocktail in an industry that sells much less than that of the car and operates in reduced volumes. In short, the motorcycle industry has focused on gasoline engines Because of its ease to extract power in low displacement, the advantage in weight-power relation, and the finely important performance in a vehicle in which, literally, we have the engine under the legs. Diesel attempts. Attempts to create a diesel motorcycle are over a hundred years old. Already in 1904, Holland created a diesel engine with a single cylinder, 2 hp of power and turned to 700 rpm. It was basically a bicycle with the support of a small engine Since then, there have been multiple attempts to make the diesel motorcycle profitable. The giant Royal Enfield He was one of them, with his 350cc diesel bullet. The conclusion they obtained was clear: “Although the sales of our gasoline motorcycles grow with the market, diesel have not followed the pace. It was a niche product. Now I don’t think we continue with the motorcycle” They are, everything is said. Axiom diesel cycles wants to try again. Matthew Lach, creator of AXIOM DIESEL CYCLEShe continues to believe in the dream of diesel motorcycles, and has materialized his own concept. Your company has been manufacturing custom motorcycles with this type of engines since 2019. Real, for street and perfectly accessible … for anyone who wants to pay them. And it is that the price of one of their custom diesel has a price that is around $ 50,000. There is not a single motorcycle in the generalist market that is around this figure, not even the supercar or The most enviable market trail. What you take. Far from offering a competitive engine in features regarding Its Custom Competitorsthe vision of this company is particular. It offers a three -cylinder engine, a thousand cubic centimeters and … 24cv of power. Exclusivity, an aesthetic achieved and, what noses, a diesel engine, is what this manufacturer offers that, for the moment, only sells in the United States.

The authentic battle will be fought by ia agents

by

The dispute over world supremacy that maintains US and China It permeates everything. The global economy, the most developed defense strategy, the commercial relationship between powers … and technology has an absolutely protagonist role in The delicate current geostrategic situation. Semiconductors and models of artificial intelligence (AI) are the resources used by the two countries with the greatest influence of the planet to measure its strength, and it is understandable that it is so. The range of applications in which the avant -garde and advanced AIs are crucial to guarantee the development of a country is very wide. Its scientific capacity, its industrial development, its economic competitiveness or its military power depend largely on these two resources. However, AIs are supported by semiconductors. Without integrated circuits of high density, high performance and high efficiency it is impossible to implement a really capable AI model. This is the reason why the US government is doing everything in your hand to prevent GPUs for avant -garde that design Nvidia, AMD, Intel or brains, among other companies, reach China. But for the moment the country led by Xi Jinping is resisting the pressure. Jensen Huang, the general director of Nvidia, has declared A few days ago, China is not behind in front of the US in AI. And the solvency of Deepseek, Ernie, Qwen, Pangu, Hunyuan or Sensenova endorses its analysis. The greatest growth potential is the AI ​​agents Right now it is very difficult to determine in an objective way which country leads in AI. It is reasonable to conclude that the US is ahead of China if we stick to the joint capacity and performance of its AI models, but the really relevant thing is to determine if that capacity entails a real value. This is The line of thought that defends experts As Arthur Lai, Chief of Research for Asia of the Macquarie Financial conglomerate, or Jason Corso, professor of AI at the University of Michigan (USA). The metrics that are currently used to evaluate the abilities and performance of the most advanced AI models are less and less clarifying In addition, it is important that we do not overlook that the metrics that are currently used to evaluate the abilities and performance of the most advanced AI models are less and less clarifying. And is that as The models improve and develop Its global competitiveness is equalized. During The Google I/O event last week the spokesmen of this American company said that Gemini is the fastest AI in the world because it reaches a speed of generation of Tokens ten times taller than Deepseek. An note before moving forward: the generation speed of Tokens It measures the speed with which a model of AI generates the answers, but it is only an indicator of the many that is necessary to use to evaluate the ability of an AI. Alibaba, on the other hand, assures that his last family of Qwen models surpasses his rivals if we stick to the ability with which he addresses mathematical reasoning or application programming. In this context, the most reasonable conclusion we can get is that each company affects those indicators that favor it. However, for users, the really important thing is the real value that an AI gives us. AND According to Lai, Corso and other experts The greatest growth potential has it AI agents and not so much the great language models themselves. An agent is an AI program that has been designed to make decisions for himself and behave in an autonomous way with the purpose of achieving a goal. The most important difference between an AI model and an AI agent is that the latter does not need us to tell him at every moment what he should do; Plan, analyze and execute tasks for yourself. This is the battlefield in which the companies that are dedicated to AI will compete, if they are not doing so.

From 0 to 252 km/h at 6,0542 seconds. It is not magic, it is a motorcycle that works with water

by

When one looks for the benefits of a motorcycle or a car, it is usual to meet the term “Mile room”. In Spain we are perhaps more familiar with the figure from 0 to 100 km/ho how long it takes to travel a kilometer from standing. However, the mile room, those 402 meters is the usual measure that is taken as a finish line in the Drag Races. Yes, the Acceleration races So famous in the United States in which we see artifacts of all kinds to launch from standing at impossible speeds and, in some cases, let out a parachute once the finish line has passed. As with cars, in the world of motorcycling it is also competed in these particular races. The most striking use modified motorcycles that, such as You can see in this videothey have a huge distance between wheel and wheel and gigantic tires. The objective: maximum traction and aerodynamics to achieve the highest speed in the shortest possible time. If this does not seem striking enough, you still have to meet Graham Sykes, a pilot who has managed to cover the 402 meters of the mile room in six seconds reaching a tip of 252 km/h. Figures that become difficult to assimilate and impossible to believe for a steam motorcycle. That? At 252 km/h with water as fuel “We did the first 18 meters in 0.73 seconds, 100 meters in 1.99, 201 meters at 3.2 and 402 meters in 6.05” With these words, as the one who describes the figures pointed on an excelll sheet, Graham Sykes had his experience aboard the “Force of Nature”the faster steam motorcycle ever built, they collect in Motorpasion motorcycle. Sykes explained at the end of the test he had achieved beat your own record and had reached 201 meters faster than anyone aboard a steam motorcycle. The eighth mile, those just over 200 meters, is another of the usual distances in this type of racing. Although it is far from the world record on a motorcycle Dragster (less than five seconds and 469 km/h of peak speed) the merit is double because it is built in the house garage only for exhibition purposes. And warns: “We are very close to running the 402 meters in five seconds. We really want to finish the great engine at the end of this year, with 120 liters of water and three seconds of power. “Because the current motorcycle only has a water tank of 88 liters and generates its maximum power for 1.9 seconds. Yes, it’s talking about water. Because that is a steam motorcycle, right? In which it moves with water. How do you do it? They explain in Motorpasion motorcycle that the system is as simple as water, heat and pressure. To heat the water they use hydrogenated vegetable oil to produce pressure. This accumulates until being expelled by a Laval nozzle. At that time, overheated steam is in charge of throwing the motorcycle at more than 250 km/h. In fact, according to Sykes, the motorcycle can reach up to 320 km/h (once the mile room is exceeded) and is trying to increase the capacity up to 130 liters of tank and with two heating pipes Take the water up to 200ºC of temperature and generate 30 pressure bars. Objective: break the barrier of six seconds in 402 meters. Photo | CPE In Xataka | The crazy and crazy story of nuclear cars: the projects that played to be God during the twentieth century

The great AI companies have declared a underground war to a pillar of education: human teachers

by

We would all like to have a Keating Professor In our lives. One that made us get on the desks to see things from a different perspective and that he would teach us that the most important lesson he has for us is summarized in the words “Carpe Diem”. There are very few who approach that image, but all of them, bad or good, threatens them the same future as Other professions: Be replaced by an AI. Professor 24/7. The narrative of several AI companies is clear: the human teacher is a bottleneck. Each of them serves many students, their knowledge is limited and their finite availability. The AI, they assure those companies, proposes a remarkable alternative. Personalized professors 24/7 with infinite patience and access to all the knowledge of the world. There is a clear problem: that message devalues ​​the teacher’s function as a guide, mentor and catalyst for curiosity and reduces it to a mere transmitter of information. Continuous evaluations. Another of the pillars of the educational system – and one of the tasks that most consumes the teaching staff – is Student evaluation. The AI ​​promises to correct efficiently, massively and immediately, releasing the teacher for other tasks. But again in human evaluation there is much more than a mere correction of errors. The effort, the reasoning process, creativity, originality or even the personal context of the student are evaluated. Biases also pose a clear threat to these evaluations, in addition to promoting a model Based on the correct answer and not in the reflexive process. My school is OpenAi. So far schools, universities and other academic institutions are the guarantors of a theoretically coherent and quality curriculum. The approach of the companies of AI would be that of Become them In “Guardians of knowledge” deciding what is important to learn and how. The risk: lead to a fragmented education and dictated by the interests of the market, eroding the role of education as a pillar of society. Threat to humanities. The AI ​​also raises the irrelevance of memorization – it can already respond to all known knowledge – and bet on skills such as “Prompt Engineering“(know how to ask things to AI) or Technical subjects (Stem). That suggests a clear impact to matters of humanities and critical thinking that we do not apply directly. Fields such as philosophy, art or social skills, hardly quantifiable, would go to the background. The objective would not be as much to train and prepare workers for the technology industry. Goodbye to social investment. Companies that bet on that model have a clear objective: climb and be profitable. AI technology applied to education promises a lot of savings (less physical infrastructure, less teachers) and a highly scalable business. But also imposes a worrying revolution to one of the pillars of society. Bill Gates believes in the future of the teachers of AI. Among the experts who outline that idea is the figure of Bill Gates, co -founder of Microsoft. His commitment to the teachers of AI It was early: Chatgpt had been in the market for just five months when he said that “AIs will reach that capacity, to be as good tutors as any human being.” For him, this technology should also be a “leveling” for society. According to Gates “having access to a tutor is too expensive for most students, especially if that tutor adapts and remembers everything you have done and review your work.” Openai and Khan Academy have the same vision. A year ago the presentation of GPT-4O surprised among other things for that capacity offered by this AI model to talk directly to him. One of the OpenAI demos, carried out in collaboration with Khan Academyhe showed Sal Khan, his founder, contemplating how his son used the model to receive a geometry lesson. The interaction was impeccable and pointed to a future full of teachers of ia locked in our tablet, our mobile or our computer. Khan is of course interested, but it doesn’t hurt see your ted talk on “how AI could save (not destroy) education.” Schools converted into nurseries. Luis von ahn, Founder of Duolingothe poular application to learn languages, it also takes time turning towards the AI. A few days ago he participated in the podcast No priorsand there he commented how although there are very good teachers, “there are not many.” For him, education will change radically because “it is much more scalable to teach with which with teachers.” Even so pointed out That does not mean that teachers disappear: “You will continue to need people who take care of students”, but focused on a new role: “I don’t think schools disappear, because you need nurseries.” Image | Buena Vista Pictures In Xataka | Towards the end of duties: how chatgpt has been inserted in the center of the great debate on education
