We have tried to use AI to verify if the images of the war between Iran and Israel were made with AI. It has been a disaster

by

False images circulate on social networks is no novelty, but in the era of AI It is increasingly difficult to detect them And they have even made Let’s distrust real photos. That photos taken with AI are viral when an important event is the new normality is; We saw it After the blackout And also with him Conflict between Israel and Iran. It is clear to us that AI is very good to generate false images, but what if we use it precisely for the contrary? Not so much. The photos in question. At the same time as a Half Iranian published The news that Iran had demolished an Israeli F-35, two images began to run like gunpowder on social networks, although We soon knew they were false. One of them, that of the star and surrounded by curious F35, is especially striking. To begin with, the proportions make no sense: the plane seems giant when actually measures 16 meters and people are larger than buildings. And that not to mention that the damage of the plane is minimal to have been shot down. These images were not the only ones generated by AI that circulated in the first days of the conflict. Several videos such as this one of a huge Iranian missile that it seems quite real until we see that the water brand has been left to see that it is made with the, or East of a tel aviv shattered. AI is terrible doing FACT-CHECK. Means dedicated to FACT-CHECKING as Damn already denied These and other images created with AI in the context of the conflict between Iran and Israel. However, there were users who tried to resort to AI tools to check the authenticity of the images and obtained quite confusing answers. Is What happened in X with Grok. An analysis of more than 130,000 posts revealed that Musk’s AI was not able to detect some false images or identify the sources from which they came. The community notes written by the users themselves were much more reliable. We have tried it. To check the AI ​​capacities, we have used the image of the disproportionate F-35 and have asked several AI tools. This is what they have answered: Chatgpt: The Openai tool begins “This image does not seem real” and then proceeds to make an analysis of the proportion of the plane, which correctly identifies as a F35, and states that the damage does not seem coherent. Perplexity: Like Chatgpt, he tells us that proportions, perspective, and airplane damage and other details suggest that the photo has been digitally manipulated. Gemini: It tells us that the image is real, but that it is not an attack in combat, but of a clash with birds that happened in Israel in 2017. When we answer that the sources show us, it happens several links to the news, but in none of them the image appears. After a while sending us confusing information, he ends up recognizing that he was wrong and apologizes for “the serious mistake.” Claude: It is the only one that states with forcefulness that the image is not real and gives us the exact context of what has happened “this is one of the many false images that have circulated as part of misinformation campaigns during the conflict between Israel and Iran.” The reliability, pending subject. In our test, Gemini has completely invented the answer, while Chatgpt and Perplexity succeed, although they do not get wet. Claude is the only one that gives us all the information and hits fully. Although language models have improved a lot in a short time, Many answers continue to be invented Despite having access to the Internet and searches. Undoubtedly, reliability is the pending subject of generative AI and where more improvement margin has.

The possibility of a nuclear disaster

by

All we know at this time is that the United States, through its president, has said that next week It will be “very important” to determine the course of war between Israel and the Islamic Republic. Meanwhile, a fear appears in the background, one that, paradoxically, even Russia has put on the table four months after Chernobyl attack: “The world is millimeters from a catastrophe”, The Ministry said of Russian Foreign Affairs. They talk about a nuclear catastrophe. Potential impact on nuclear. I counted this week The Financial Times That Israeli air attacks against Iran’s nuclear infrastructure have revived fears about a possible radiological or chemical catastrophe in the region. In that regard, the general director of the International Atomic Energy Agency, Rafael Grossi, described as “Deeply worrying” The offensive, warning that military escalation increases the risk of a radioactive release with serious consequences for the population and the environment. Although for the moment It has not been registered a large -scale radiological emergency, some incidents, such as the Complex attack Natanz uranium enrichment, have caused localized pollution within the facilities, although without affecting the outside environment, according to measurements of the nuclear agency itself. Radiological contamination The Current data indicate that the detected radioactive pollution is limited to the interior of the Natanz complex and is mainly composed of alpha particles, whose health risk is considered manageable If they are not inhaled or ingested, since their reach is reduced to direct contact with internal fabrics. In the case of Natanz, I They damaged two rooms Underground enrichment and several surface buildings, including a pilot laboratory. However, the level of radiation in the surroundings He showed no changeswhich suggests that There has been no escape external As for other key facilities Like Fordow or the heavy water reactor in construction in Khondab, I don’t know They have registered damagewhile in Isfahán it has not been detected Radiation increase After recent attacks. The difficulty of a catastrophe. The Times explained that a large explosion that releases radioactive pollutants massively requires to reach materials subjected to fissionas in an operational reactor or in an atomic pump. However, not even Bushehr nuclear power plant nor the Tehran research reactor They have been attacked so far. The enriched uranium that Iran possesses is in itself weakly radioactive and only presents greater risks in very specific conditions. The release of fission products such as radioactive iodine or CESIO-137, responsible for the worst health effects after Chernobyl in 1986it does not seem likely on the current scenario. In addition, Iran’s main nuclear facilities are designed to minimize external risks: critical areas from Natanz and Fordow They are buried under tons of concrete and earth, which makes even powerful weapons have difficulty penetrating them full. Reactor 4 Aerial Photography, several months after the explosion Chemical risks. Beyond radiation, experts point out that the real danger could be in the dispersion of toxic chemicals. In the facilities attacked, Like Natanz and Isfahánis stored and manipulated Uranium hexafluoruroa compound used in the enrichment process. Although it is stable at room temperature, its contact with water (even that of air) can produce fluorhoric gas, highly corrosive and lethal if it is inhaled. The OIEA has confirmed that in him Attack to Natanz It is possible that compounds such as uranium, uranilfluoruro and even fluorhorical gas have released compounds, although contained within the enclosure. An illustrative case was the Explosion of 1986 In a conversion plant in Oklahoma, where the liberation of hexafluoruro caused a death and pollution in the environment, demonstrating the reach of this type of accidents even outside a war context. Natanz Nuclear Facilities International regulations. In the key to the international legal framework, armed attacks against nuclear facilities for peaceful purposes are prohibited. The OIEA has reiterated on several occasions that any aggression of this type violates the principles of the United Nations Charter, the rules of the agency and international law. Both Israel and Iran form part of the OIEAalthough the first is not a signatory of the non -proliferation treaty. In 2022, the precedent of the Russian attack and subsequent occupation of the Ukrainian Central of Zaporiyia It was already pointed out by the agency as a made unprecedentedwhen it occurred in a large nuclear complex. In the case at hand, Israel justifies its actions in the suspicion that Iran is developing a nuclear weapon, an accusation that Tehran denies. For its part, the OIEA declared recently that Iran has raped by First time in twenty years Its non -proliferation obligations, adding more tension to the context. And if… Then there is another substantive issue. If the Iranian regime suddenly crumbled, leaving its enriched uranium arsenal and related materials unprotected, what would happen? Although air attacks can degrade critical infrastructure, they are not enough for themselves to guarantee the total elimination of nuclear abilities if they are dispersed or hidden. Given this scenario, they remembered the The War Zone analysts that the US special forces (particularly elite units as Delta Force and Seal Team Six) They carry years preparing to intervene on the ground in nuclear emergency situations. Since 2016, El Special Operations Command (Socom) leads the mission of counteracting weapons of mass destruction (CWMD), inheriting this function of the strategic command (Stratcom). The acquired experience From the dissolution of the USSR to ensure uncontrolled arsenals serves as a model for these new contingencies. The United States Army in Nuclear Emergency Exercises The threshold of proliferation. According to the Latest Oiea reportsIran accumulate at least 400 kilograms of 60%enriched uranium, a purity much higher than necessary for civil use (3-5%), although below 90 % required For nuclear weapons. However, moving from 60% to 90% is a relatively short technical leap. The OIEA considers that with just 92.5 kg of 60% uranium it can get a nuclear bomb behind him Final enrichment. This reality worries, since the regime has prevented inspections in all its nuclear facilities. Iran has even taken “special measures” to hide its … Read more

In a desperate attempt to avoid the blackout, Ree tried to start a gas center seven minutes before the disaster

by

The Official reports on the blackout They reveal the maneuvers to counterreloj that the network operator did to try to stabilize the system while rushing into the collapse. T-7 minutes. In the moments of maximum tension (never better) prior to the historic blackout that left the Iberian Peninsula without light on April 28, Red Electric took a desperate measure: he ordered the start of a combined gas cycle center to try to stabilize an electrical system that crumbled at times. The call to the owner of the plant, registered in official reportsthere was just seven minutes before the system collapsed completely at 12:33 at noon. However, the thermal power plant never coupled then The zero of tension It occurred first. It was not a typical morning. That April 28 were the perfect conditions to test the network: a relatively low energy demand, and a very high solar radiation that caused a massive predominance of photovoltaic generation. With a network dominated by the electronics of investors instead of the heavy turbines of the conventional generation, the tension already issued warning signals. At 11:00 in the morning, after a voltage climb, the transformers of two Adif substations in Zaragoza were fired. But the situation became critical from 12:00, with the appearance of strong frequency oscillations that put the stability of the entire network in check. The oscillations. At 12:03, a first 0.6 Hz oscillation was detected, an unusual phenomenon that lasted for almost five minutes, forcing Red Eléctrica to take emergency measures. Among them, reduce electricity exchanges with France and Portugal. It didn’t help much. At 12:19, a new 0.2 Hz oscillation shook the system. Given the seriousness of the situation and the need to “attach more conventional generation” to control the tension, Red Electrico contacted at 12:26 with the head of a combined cycle center in Andalusia to start urgently. The choice was not accidental. The group that could be attached faster in the southern zone was sought, one of the most affected by instability. The chosen central, which had decoupled at 9:00 in the morning, was “hot”, which allowed it a shorter start time: an hour and a half. The goal was to be fully operational at 2:00 p.m. Unfortunately, the system did not have that time. Just seven minutes after the starter order was given, at 12:33, a succession of waterfall generation, mainly due to surgeens, caused the total collapse of the peninsular electrical system. The measure, a last resort to avoid the greatest blackout in the recent history of Spain, “never consummated by the zero of tension.” Image | HRAD (CC by-SA 3.0) In Xataka | Many plants disconnected from the network when the blackout began. The problem is that some renewable did it before

I had no idea how to execute a local AI and I just did it in five minutes with my Android. It has been a disaster

by

The career of whom he manufactures The most capable smartphone It will not be alone in its components: AI has become an essential absolute To win this battle. Gemini He is the absolute protagonist, both in Android and in an iOS in which The presence of AI is insignificant. A complete and capable assistant, with the requirement of being permanently connected to the Internet. Google, Gemini’s mother, has decided Give 100% local models a chance in Android. Including those of its competitors. I, who had never executed a local AI on a PC, I have been able to achieve it on my phone in five minutes. 10 Google applications that could have triumphed Installing Google ai Edge Gallery Google has released an open source app so that any user can interact with multimodal AI models. It is completely free, has no publicity, and its only limitation is that it is not published in Google Play Store. You have to Download it from github. It is as easy as clicking on the link and downloading the file, which weighs 115 MB. Once you have downloaded it, click on it and install like any other app. Depending on the customization layer you use and the browser from which you download it, it is possible that the system asks for the occasional permission. Give it without fear, since it is a clean Google app. Once installed, the app will be in the application drawer or desktop of your phone, depending on your layer. Just open it and download the available models to start using it. Using the local AI in my Android This application allows you to use four predetermined models of the local AI: GEMMA-3N-E2B-IT-Int4 GEMMA-3N-E4B-IT-IN4 GEMMA3-1B-IT-Q4 Qwen2.5-1.5b-Instruct Q8 Each of these names is very likely to sound to Chinese, but there is a very simple summary. Gemma are the Google models, and the number behind “E2B, E4B, 1b”, refers to the parameter number of each model (2 billion, 4,000 million, 1,000 million). This means that, in order, Gemma 3 1b is the fastest, but more basic model, followed by E2B and with E4B to the head as the most complete. On the Qwen side, it is a Chinese model developed by Alibaba, with 1.5 billion parameters, and quite logical precision. These are the models that the app brings, but we can install models on our own. What I win and what I lose using the local The Google app is designed to execute three scenarios of use: Images questions: problem solving, identifying objects, etc. Prompt Lab for summaries, rewriting texts and code generation. Ai Chat: Multi -urnal conversations with AI The local AI is somewhat more limited in these scenarios of use, but in return it is more private. It runs 100% on your phone, without connection to servers. This minimizes response latency, something that I wanted to verify with a fairly simple test: the translation of a text not too extensive. “If the computing power on each chip continue to grow exponentially, Moore real Demanded Were Useful in Business Applications, Too. Defense Contractors Thought About Chips Mostly As a Product that Could Replace Older Electronics in All The Military Systems. “WHEN US DEFENSE SECRETARY ROBERT MCNAMARA REFORMED MILITARY PROCUREMENT TO CUT COSTS IN THE EARLY 1960S, CAUSING WHAT SUB IN THE ELECTRONICS INDUSTRY CALLED THE” MCNAMARA DEPRESSION, “FAIRCHILD’S VISION OF CHIPS FOR CIVILS SEEMED PRISON Off-The-Shelf Integrated Circuits for Civilian Customers Even Sold Products Below Manufacturing Cost, Hoping to convince more customers to trym. “ Chatgpt (4th): 5 seconds Deepseek: 19 seconds The local Google (Gemma 3 1b): has not understood the instruction. Google local (Gemma 3 E2b): 26 seconds. Google local (Gemma 3 E4b): 34 seconds. Google local (Qwen 2.5): 16 seconds. The results are quite irregularand that is that the app is in its initial stage. The main problem I have found is that sometimes it is difficult for him to execute the model, even in cases of light models such as Qwen. In a Samsung Galaxy S25 Ultra I had to restart the app on some occasion, since I did not execute the prompt. I have also wanted to prove how simple problems solve with the visual understanding of images, using the heavy model E4B of Gemma. It has also been quite disaster. In the first attempt I have asked him to solve all the problems. He has succeeded. In the second, I have asked him to solve only the first. He was wrong and, after telling him that it was wrong, he has err. Yes, he does a good job recognizing elements in the images, but it still has a hard time going further (Google just lets his Gemma models choose for these tasks). The conversational assistant works well, with its limitations, but well. It serves to talk and help us with any task that we can think of that you do not need a real -time search on the Internet. If you are especially jealous with your privacy, and want to execute the without any server connection, it is a relatively valid alternative. Google has this app as a test laboratory. At least for now it is not a real alternative, much less, to Gemini.

Old, without maintaining and without ITV. One in four motorcycles in Spain is a disaster for road safety

by

Near one in four motorcycles of less than 25 years circulate without the Technical Inspection of Vehicles (ITV) in force, according to figures published by the DGT and collected by Motorpasionmoto. Being more precise, 23.3% of registered motorcycles circulate on the roads without having passed through the ITV. The worst news? The data falls short: not even all motorcycles are represented in that percentage. ITV are the parents. According to Spanish ITV data about 25% of motorcycles circulate without ITV in our country. This fact only refers to those with an age of less than 25 years. All those that have a higher age are not reflected within statistics. These are precisely the ones that represent the greatest risk, due to possible wear of their consumables and lack of maintenance. According to Guillermo Magaz, director of AECA-ITV, the old vehicles are the ones that most breached the corresponding reviews. An aged park. 16.9 years. This is the Middle Ages of the Motorcycle Park in Spain. It is a figure even higher than that of The age of cars in our countryalthough with a certain sense given the two NATURALS OF THE MOTORCYCLE: A vehicle to move from A a B as economical as possible or a simple vehicle bought by pure leisure. The consequences. In 2024 the number of deaths in Moto amounted to 289, higher figure from 2015 records. Beyond the relationship between a well maintained vehicle and their safety, there is a key fact to take into account: insurers do not have to cover a single expense if the vehicle has not passed the ITV. In case of an accident, without the inspection in force, the insurer has no legal obligation to cover the expense. The fines. The DGT fight with vehicles without ITV does not cease. It is a practice that can lead up to 500 euros of a fine, depending on the case. Circular without ITV: 200 euros, 100 euros with soon payment. Circular with unfavorable ITV: 200 euros, 100 euros with soon payment. Circular with negative ITV: 500 euros and vehicle immobilization, 250 euros soon payment. It is a problem of approach: it is cheaper circular without ITV than to circulate with a negative ITV vehicle (to which they have thrown back in the ITFV). The DGT He has been asking for years That insurers check if the ITV is in force when securing and renewing, although they have not been too successful. Meanwhile. In the absence of ITV, good security measures are good. The airbag It will become mandatory in driving examsonly the use of Integral Helmet on the roadand the validations of the card B to drive 125cc motorcycles They have ended.

that of 1755, the disaster that destroyed the city and changed science

by

Earthquakes in Lisbon can be more or less intenseto have greater or lesser reach and unleash or not alarm, but since the mid -eighteenth century all (whether strong, medium or slight) have something in common: in addition to stirring the ground, they remove the memory. Ease in the Portuguese capital is synonymous with 1755. of disaster. Of destruction. Of Thousands of dead. And also, in its own way, of regeneration. It is so for a very simple reason: in Lisbon it is impossible for the soil to be stirred without the Lisbon remembers The drama that their great -grandparents lived (and perhaps some more tátara) on all the saints of 1755, when in a matter of a few hours the city trembled, burned and sank. Literally. The tremor recorded yesterday afternoon in the Lisbon Metropolitan Areaof Magnitude 4.7 And to which two other mild ones have happened today, 2.8 and 2.3they are no exception and (as has already happened with another similar In August of magnitude 5,3) dusting the memory of 1755. A November morning … The history of the earthquake that He swept Lisbon In 1755, there has been thousands of times and in almost all chronicles a circumstance is highlighted that continues to fascinate even today, 270 years after the disaster: its date. The ground trembled on the morning of November 1, All Saints’ Day, with the devotees Catholics praying in the temples and large amount of candles lit in honor of the deceased. Maybe it seems silly, but ultimately it turned out A key detail. Thanks to testimonies such as the English Reverend Charles Davywho remembered that autumal morning prior to the earthquake as the “most beautiful”, we know that Towards 9.30 a.m. The Lisbon gathered in the city’s temples felt a rumble. The noise was so intense, so loud, that Davy believed that it was a carriage march. “I soon disappointed myself, I discovered that it was due to a type of strange and frightening noise underground, similar to distant and hollow rumble of a thunder “, He recalled The British. It was right. That rumble was not caused by the wheels and horses of the horses as they moved on the cobblestone of Lisbon, but an earthquake that the researchers They still study today. In July 2021, without going any further, Nature public An article that deepened in Its causes and tectonic origin. What neither Davy nor the rest of the inhabitants of Lisbon could know in 1755 is that the city would not be shaken by a single earthquake. They happened two or three tremors Of which the second was, from afar, the most intense. Today it is estimated that it reached a magnitude of between 8.5 and 9 On the Richter scale, almost double that it shook yesterday the capital and superior to the one that hit Morocco in 2023. From the Institut de Ciènces del Mar They clarify In fact, one of the natural events is considered ” more destructive in history from Europe “. Temples fell. Palacios fell. Public buildings fell. And houses fell. Earthquakes and something else 1755 Maybe it is far behind in time, but the Lisbon of then reacted to the tremors in the same way that we would do today: they sought refuge. A good part of the survivors of the first earthquake, regardless of sex or rank ran to the great open square next to the Tajo River. There Mr. Braddick, an English merchant whose testimony He rescued years ago The BBC was found to swirled. There they cried mercy to heaven. And there they were surprised by the second shock of the ground, which like Braddick tells, “The ruin completed” of the buildings that had already been damaged. It is not necessary to imagine it. One of the forced stops for tourists visiting Lisbon is naked Gothic arcade of the church of Convent do carmoone of the architectural victims of that unfortunate day. Just as if a drama in three acts were, the earthquakes that shook Lisbon’s foundations were only the beginning. The earthquake generated a tsamot with waves of between six and nine meters(It was felt Also in Cádizleaving thousands of victims) that unloaded violently in the lower part of the city. In less than an hour The water crashed into the Paseo Marítimo, where it surprised not a few Lisbon who had sought refuge in La Ribera. There is even more. The disaster was accompanied by fires that were probably aggravated by the overturned stoves and the vote candles lit for the deceased. Years ago the National Geographic Institute published A monograph in which the devastation generated by the flames, which lasted for five or six days. “As soon as it obscured, the entire city It seemed to shinewith such a bright light that could be read. You could say without exaggeration that there were fires in at least one hundred places at the same time “, Reverend Davy recountswho confirms that the fires lasted almost a week, “without interruption.” A tragedy and a change The result? Just a few years later Voltaire I pointed critically in his work Naive that the disaster had taken “three quarters” of Lisbon. Other sources They go further And they suggest that the tremors, the tsunami and the fire “almost completely” the Portuguese capital and knocked down around 12,000 homes. The balance is in any case bleak, just like the balance of victims. Depending on the source that is handled, there is talk of 10,000 Deaths, 30,000, 60,000 or even 90,000. A barbarity if one takes into account that at that time Lisbon would have between 200,000 and 300,000 inhabitants. Such was the debacle that is told that Sebastião José de Carvalho e Melo, Marqués de Pombalhe advised King José I be pragmatic: he played “rescue the living and bury the dead.” The 1755 disaster was not only felt in the balance of deaths, injured, missing and buildings, squares, roads and crumbled temples.
