Some scientists have reviewed 99 studies on intermittent fasting. Its results are not very optimistic

by

The popularity of intermittent fasting has grown over the last years, partly by a series of scientific studies that endorsed their potential when helping us lose weight. However, sometimes the results of individual studies do not agree with the global image of the matter. Not so effective. A new study has in doubt The ability of intermittent fasting as a superior way of losing weight. The analysis concluded that, although some forms of intermittent fasting could offer a slight advantage, the results obtained with these were not significantly better than those obtained with the simple caloric restriction. The intermittent fasting. The concept intermittent fasting It refers to a series of diets based on a temporary caloric restriction. We cannot speak of a single flash form since this temporary restriction can occur in several ways. Conventional forms of intermittent fasting imply not consuming any food during a specific time window, more or less broad, in certain days, which can be alternate or successive and in different proportions. It can also refer to drastically restricting the calories we consume in certain days of the week. Sometimes a non -intermittent hourly restriction is also included in these diets, that is, a more conventional fast. Review and meta -analysis. Evaluating the effect of these diets is not easy, but over the last decades, various teams of researchers have launched to it, obtaining very diverse results and sometimes even contradictory. Solving this type of discrepancies is what is sought with the tool we call meta -analysis. Metaanalysis start from a systematic review of literature in which the team compiles all studies in the field in a specific time interval. Metaanalysis consists in the statistical evaluation of the results obtained in compiled quantitative studies to obtain an average effect through a broader sample which allows strength to the conclusions. In other words, solve discrepancies. 6,582 participants. In this case the meta -analysis included 99 studies individuals that added in total 6,582 participants. As explained by the team responsible for the new study, among these participants, the average body mass index was 31 and about 90% had some health disease or condition. The results showed that fasting on alternate days (restricting our food consumption to alternate days) was the only option that showed an observable benefit in weight reduction. However, this reduction (1.29 kg on average) did not exceed the 2 kg threshold defined by the study responsible for the study. The details of the study were published In an article In the magazine BMJ. 99 studies, and we still need more. Metaanalysis usually serve to settle scientific knowledge in one subject, but at least in this case it is still more to investigate, admits the responsible team. The heterogeneity of dietary strategies, the small size of the samples and the limited evidence are limiting factors indicated by the team. “The evidence today provides some indication that diets based on intermittent fasting have continuous energy restriction benefits for weight loss and cardiomethabolic factors. Explain the team. In Xataka | What if we are doing the bad intermittent fasting? Some experts propose to focus only on carbohydrates Image | Xataka with Gemini / I Yunmai

His passage through the United States has been a failure

by

It began to glimpse since last April the ugly things were put on. Renfe’s adventure in the United States has ended. He does it without carrying out the great project they had and confirming millionaire losses even though no train ever shot. The project. A high speed line 386 kilometers between Dallas and Houston. That was the great project that Renfe had in mind to enter the US market, a market that seemed perfect because it lacks high -speed roads among large cities. Dallas and Houston are two of the cities that generate more money in the United States So in European eyes it seemed a round business. The intention was to launch a train that reached a maximum of 386 km/Hy joined both cities in less than an hour and a half with an intermediate stop. A not so good idea. But although the business seems evident to European eyes, the thing is not so simple seen from the American perspective. To have, throughout the United States there is not a single high -speed line that connect large cities as we understand in Europe or Asia. In fact, the highest speed is reached in a line in Florida (between Orlando and Miami) that, for just 32 kilometers, is traveling to a maximum of 201 km/h. Then, the speed falls again. And although there is various projects underwayUSA It is still a desert for high speed. Bye. After more than a five years, the project has been completed, the operations of Renfe of America have completed, they point out in electionomista.es. The company had created a subsidiary in the country to take the reins of a project that, they assured, could generate 5.3 billion euros before 2042. In Aprilhowever, it was already guessed what was going to be the end of Renfe’s American adventure. So be Duffy, Secretary of Transportation, confirmed with a statement that denied the help of 63.9 million dollars that was pending to surrender (it was already approved) because “the financing of this project is a waste of taxpayers’ funds and a distraction of the main mission of Amtrak to improve their existing deficient services.” That help was key to continue advancing in the high -speed railway corridor project of Amtrak Texas that Renfe had entered fully into 2021. More and more involvement. The origin of Renfe’s landing in the United States must be sought before. In 2018the company arrives as an advisor to carry out the project, imposing itself on other companies in the contest as a trainitalia. The initial contract required Renfe’s involvement for 18 months and, subsequently, the works would begin. However, with the project at the dead point, In 2021 the conditions were extended Initials and Renfe open their subsidiary in the country to gain presence in it, positioning itself as a commercial exploiter of the line. No more public money. However, the project still needed public money for construction, which did not finish please the country’s transport department. To support the withdrawal Of the more than 60 million public funds it was stressed that the project was born with an exclusively private vocation but threatened to assume the taxpayer an expense of up to 40,000 million dollars. Now, Renfe has ended up folding its operations, reflecting in its 2024 accounts extraordinary losses of 4.5 million euros and a 100% deterioration on investments undertaken for more than a five years, they point out in electionomista.es.

Whenever there has been war in the Middle East the price of oil has shot. Now something different is happening

by

A truce between Iran and Israel announced by President Donald Trump had an immediate impact on energy markets. According to Financial TimesBrent’s crude oil fell up to 5.6 % on the morning of Tuesday, June 24 – having $ 67.50 per barrel – after the news of the high to fire. However, market volatility has not ceased during the day. Prices have partially rebound after Israel accused Iran of raping the truce and threatened with a “blunt response.” At the end of the day, According to Oilprice dataBrent’s price remains around 67 dollars. This sway reflects how the oil market is still extremely sensitive to geopolitical holders. Hadn’t they shot each other? Less than two months ago, A perfect sinking storm The price of oil below $ 60, for tariffs, refinery closure and overproduction. With the outbreak of the conflict between Iran and Israel, oil prices They had shot. As He explained Bloomberg, the military offensive revived one of the greatest fears of the oil market: an interruption of the supply from Iran, the third largest producer in the region. However, that climb lasted little, exceeding the breeze price of $ 80 per barrel only for a few hours. Operators did not detect concrete damage to critical infrastructures or interruptions in crude oil flow, which quickly cooled expectations. A persistent threat. Despite the initial containment, the Ormuz Strait remains the great friction point. For this narrow one – just 9 kilometers at its closest point – circulates around 20 % of the world crude. Iran has repeatedly threatened to close it if the scale scale, which would activate one of the worst scenarios for global markets. The tension has generated concrete reactions. Several Chinese oil ships They have received instructions to avoid the area. This gesture suggests that, although there is still no open conflict, navigation risks are real and affect logistic decisions of key actors such as China. There is a superlative difference. Despite tensions, prices have not climbed as in past crises. This is due to several structural factors such as high production and sufficient reserves. Thanks to the rise of Shale Oil in the US and the increase in production in Canada, Guyana and Brazil, the global market has a wide mattress. Even if Iranian exports were stopped – about 2 million barrels per day – OPEC+ could supply the void without great shocks, According to Bloomberg. On the other hand, in the same medium, they have stressed that even China, the largest oil consumer in the last decades, shows signs of having reached a roof in its demand, added to its own national production. A fragile balance. The immediate future of the oil market will depend on three major factors. The first, and more critical, is the Ormuz Strait: if Iran decides to close – or threats credible with doing it – this strategic route, prices could be shot. Second, there is the response from the United States and Israel. If the truce is officially broken or military reprisals intensify, a new cycle of uncertainty and volatility in markets would open. Finally, China’s position, the main Iranian crude buyer. Any decision of Beijing – is a tactical withdrawal, greater caution in transport or diplomatic pressure – could alter the current balance. For now, operators seem to assume that the situation will remain contained, without a real interruption of the supply. But with the atmosphere so loaded, a single spark could return to oil to the center of the hurricane.

China has commissioned the largest battery of all its electricity network to an unexpected company: Tesla

by

China has no problem parking Commercial tensions with the United States If it is for the benefit of the country. And the country needs Tesla for an increasingly pressing task: stabilize a network with more and more renewable participation. The largest battery in the largest network. China has selected Tesla to develop what will be the largest energy storage station at network scale throughout the country, surpassing the 1 GWh battery park in Shandong. The American giant He signed an agreement with the local government of Shanghai for 4,000 million yuan, 557 million dollars, to lift a gigantic station that can actively participate in the spot electricity market. China has the largest electricity grid and a renewable energy generation capacity in constant and massive growth. The Tesla battery station You can buy and store energy When demand and price are low, and then sell it to the network during consumption peaks, helping to balance supply and demand, and improving the general stability of the system. The business is in the megapacks. The Energy Division of Tesla does not stop growing, to the point of become a fundamental pillar of the company. The project engine is megapacks, Large storage units in 3.9 MWh batteries which can be used to stabilize the electricity grid and avoid supply cuts. It is no accident that the most ambitious battery station in China will be built in Shanghai. Just four months ago, Tesla launched a new Megapacks factory in the Lin-Gang area, where is also its car factory “Gigafactory Shanghai”. The new “Megafactory” is the first plant of this type out of the United States, and although it has barely been operational since February, it has already produced more than 100 megapacks. Tesla gets into the patio of Catl and Byd. They are “only business”, but the movement is still striking considering that Tesla is competing with Catl and Bydthe two Chinese giants who take 54% of the world battery market. Another way to see it is that China needs many batteries By the end of the year, the government expects to reach 40 GW of storage. But taking into account that the country installs half of the entire new capacity for renewables (329 GW in 2024), by the time the Tesla battery station in Shanghai enters service, the goal will have continued to rise. And Tesla will be just one of the puzzle pieces. Image | Tesla In Xataka | China manufactures more batteries than anyone. The problem: they accumulate next to the solar panels without storing energy

Patients lead to the operating room photos of their “improved” with AI. Surgeons are in charge of making them come true

by

A year ago, an unpublished contest copied The covers of different media: Miss Ia. As one can intuit, the models were created with artificial intelligence and presented impossible bodies: without wrinkles, without pores, without history … the event, promoted by the platform Fanvue World AI Creator AwardsNo only generated a flood of comments, but opened a deep debate: are we willing to accept something of beauty as an ideal that does not even exist? And something further, does the real body begin to be seen as a defective version of the digital render? Unreal expectations. According to The Columbus Dispatchplastic surgeons such as Dr. Jaclyn Tomsic and Dr. Craig Lehrman are observing a worrying phenomenon in their consultations: patients who come with images generated by AI, asking for impossible interventions. “With AI you can make your body as you want,” explained Tomsic, maxillofacial surgeon in Cleveland. For his part, Lehrman, a plastic surgeon at the Wexner Medical Center of the Ohio State University, has reported cases of older patients who carry photos of edited celebrities. “They tell me: ‘Why don’t I look like this?’ Both doctors have recognized that they have had to dedicate more and more time to explain why they cannot replicate what IA promises: biology, bone structure or age cannot be erased with scalpel. Beyond. The expectations created by filters, apps and image generators They are generating Frustration and danger: some people insist on operating again and again, chasing a non -existent ideal. In addition, they have warned of a psychological risk: people who fail to resemble these artificial images can become obsessed, resort to multiple surgeries and face constant frustration. Lehrman has summarized it as follows: “That will take many unhappy people and pursue this imaginary dream.” In fact, this phenomenon goes beyond the surgical: it affects the way we interact with our own image. It is increasingly common for people to ask AI that value their physical appearance Or tell them what to improve on your face. The point is not what the AI ​​can respond, but the fact that your judgment has so much weight on how we can perceive. Fiction made leather. Before, manipulating an image required technical knowledge or tricks of light and makeup. Today, with a free app, anyone can be seen as a supermodel in seconds. The AI ​​not only retouches, but has led it to another level: it can generate faces from scratch. According to Lehrmanthis makes it “increasingly difficult to distinguish the real from the invented.” Given this threat, the American Society of Plastic Surgeons has created a gallery with real photos before and after procedures to combat misinformation. But the battle is unequal: millions of false, stylized and standardized images are generated every day. The Aitana case. This logic is reflected in phenomena such as Aitana LópezSpanish influencer with more than 350 thousand followers on Instagram that does not really exist. In other words, it is a 100% model generated with AI. Its creators They have admitted They sought to create an influencer that “never gets tired, never ages, always smile.” With his success, he has not only obtained real advertising contracts; It has also imposed a new quite problematic aesthetic standard because there are no human limitations. Advances and dilemmas. The “artificial intelligence in plastic surgery: where do we stand?” has reviewed 96 Studies on the use of AI in plastic surgery. Although it has proven useful in diagnoses of dermatological diseases, surgical planning and even prediction of postoperative complications. However, the conclusions have also warned about ethical risks, lack of regulation and algorithmic biases. One of the key problems is that AI models are trained with limited populations data, which can generate racist, class or capacitist results. The bias behind the AI. The algorithms are trained with millions of images that reinforce Eurocentric, thin, cis and young people. As has warned Kenig et al. Quoted in the study, AI can exacerbate inequalities by replicating stereotypes invisible other bodies. This concern has also been pointed out by critical voices within the technological field. For example, author Ruha Benjamin holds that “Algorithmic discrimination does not need hate to function; You only need data from the past ”, in his book Race AFter Technology. For his part, Safiya Noble, in Algorithms of Oppression, has detailed How commercial and racist logic are embedded in search engines and recommendation systems. Technology, far from democratizing beauty, seems to strengthen it even more. The definition of beauty is not so much. As Bell Hooks said: “Representation matters.” However, if now the AI, trained with exclusion patterns, decides what faces we see, what bodies are shown, and which do not, then we are not only attending an aesthetic change, but to a deep reconfiguration of what we consider desirable, possible and human. The issue is not asking: “What is beautiful?”, But what are we willing to obey?

The wolf hunting throughout Spain depended on a red button that changes its status. And Europe has decided to press it

by

The wolf has just seen how his future is complicated in European soil. And not because of pollution, global warming, a new disease that affects herds or the loss of their ecosystem. No. The key is in the EU Official Gazettewhich has just published the directive that degrades the status of protection of the species, passing it from “strictly protected” to only “protected”. Maybe it sounds like a smaller detail or pure community bureaucracy, but In the case of Spain It will allow hunters to reduce animals throughout the country. The reason: a chain of legal changes. What happened? After years of controversypolitical anger and a rifirrafe attempt between environmentalists and hunters, over the last months the wolf has seen how cracks opened in the legal armor that protected him from the hunters. And the reason must be sought in a series of decisions adopted nationally and community. In the case of Spain, one of the key steps to reduce the protection of the wolf In Marchduring the processing of the Law on Food Waste in Congress. Now there has been a new step in that same direction, but at the broader level, with a change that It has just officialized he EU Official Gazette. And what change is that? Basically degrades The status of the Canis lupus. Instead of being considered a “strictly protected species”, as until now, it appears in the list of “protected”. Without more. It may seem like a small adjustment, but in practice it supposes that the wolf will appear without nuances in the list of animals that “can be subject to management measures.” That is, hunt. The European directive was approved a few days ago, June 17but just officialize in the EU Official Gazetteas He has revealed eldiario.es. Again it may seem simple bureaucratic, but it has important repercussions: from now on it opens a period of 20 days For the entry into force of change, so on July 14 the wolf will have lost its “strictly protected” status. Is it a novelty? Yes. And no. The change made in the Habitat Directive to beginning of this month And his recent publication in “The Community Boe” are important news for their impact, but they will actually surprise few. The wolf’s legal armor has been a reason for debate at European level. The controversy can be at least 2022, when the president of the CE, Ursula von der Leyen, lost his favorite pony for the attack of a wolf. That same year Brussels commissioned a “In -depth analysis” on the increase of the species in the continent thanks to its legal armor against the hunters. What was your conclusion? “The concentration of wolves in some European regions has become a real danger to cattle and, potentially, also for humans”, He reflected Von der Leyen in 2023. In the same statement, the CE encouraged local authorities to “take measures when necessary.” What happened since then? That community machinery has continued working on the subject. TO late 2024 The Permanent Committee of the Berna Agreement voted in favor of the EU proposal to reduce the wolf protection status, so that it passed from “strictly protected” to only “protected”, and In March The Commission moved again to propose that this change was transferred to its Habitats directiveadaptation that He received green light This same month. And what happens in Spain? The wolf has not only been the protagonist of community policy. Throughout the last years it has also served to warm the debate in Spain, where environmentalists, hunters or the parliamentary arch itself differs on the degree of protection that the species must enjoy in the Peninsula. Ecologists in action He thinks for example, authorizing his hunt “turns his back on science.” For the RFF it will help the “coexistence” With the farmers. With that backdrop, three months ago Congress adopted a series of fundamental measures for the future of the wolf in our country. The most immediate affected the herds located north of the Duero River. The lower house He endorsed A change in The Royal Decree that develops the Lespre to eliminate the protection of the animals located in that territory and that the autonomies can decide on their hunting. In practice that meant returning them to the situation in which they were before 2021. And what happens to the south of the Duero? It is there where there will be news from now on. In March Congress He opened the door Also to be reduced by the protection of the wolf to the south of the Duero, but as long as its community protection is reduced before, something that has just been formalized. In that way The species comes out of the special protection regime list also south of the Duero River. Interestingly, the Congress of Deputies made the decision while processed a law on food waste management. The reason: the promoters of the amendment that made possible the change in the Statute of the Wolf They argued that the attacks of the wolves to the cattle generate thousands of kilos of lost meat.

Huawei states that he is staying behind the chips. It is just what we want us to create

by

Huawei doesn’t like to get attention. He doesn’t want headlines. It is not generating too many and since 2019 The US veto and google occur The company has adopted a low profile and a shy, silent narrative. But as long as he does, Huawei does not stop growing and consolidating his role as one of the most important technology companies in the world. The silent leader. Ren Zhengfei (Anshun, 1944) founded Huawei in 1987 and is not only the company’s CEO: he is considered a spiritual leader. He doesn’t see it like that and affirms which is rather “a puppet leader (…). It only develops a symbolic role, like an idol of cement in a temple. Without it the temple would seem empty, but in reality the idol does nothing … that I am in Huawei or in Huawei has no real impact.” Who wants to be forgotten. Despite its absolute relevance, whether symbolic or not, Zhengfei has no intention of being in the foreground. His hope is in fact end up being forgotten. “I am just an old man. What is the point of reminding me? People should think more about the future and the world. My greatest desire is to have a coffee in a cafeteria without anyone noticing.” Zhengfei is known for his reserved and discreet character, and has transferred that way of being to his company. “Our chips are a generation behind the US”. The phrase is from the aforementioned Ren Zhengfei, which In an interview In the Chinese state media People’s Daily talked about his latest advances in semiconductors. There the head of this giant explained that the sanctions that prevent Huawei from obtaining or manufacturing state -of -the -art chips cause that “our chip continues a generation behind the US.” Better not believe it much. Huawei is Property of your employees And he has ties with the Popular Chinese Liberation Army, the country’s armed forces, of which Ren Zhengfei was part for several years. The commercial war has caused the company to adopt a very discreet profile, and REN’s comment on the state of its chips is possibly a strategy not to attract attention. Because although there may still be differences with the advances of the US, the Chinese giant does not stop expanding. For all without being noticed. I explained it William Huo, an expert who explained in China how Huawei is currently 25,000 million dollars a year on R&D. One of the results of these investments have been New Ascend chips for ia that has not been designed to overcome Nvidia chips, but to climb big. And there is a blunt example. Source: Semiianalysis Cloudmatrix 384. Huawei chips may not be so powerful, but their clusters are. It is demonstrated by the cloudmatrix 384, direct competitor of the NVIDIA GB200 NVL72. This monster has 384 GPUS Ascend 910C connected through an optical network that allows an interconnection at speeds much larger than those offered by copper cables of the Nvidia cluster. But it is also a complete cloudmatrix 384 system, as indicated in Semiianalysisoffer up to 300 flops (in BF16 accuracy) of computing, almost double what the NVL72 GB200 of NVIDIA offers. Not only that: it has the memory capacity 3.6 times and 2.1x times the memory bandwidth. The Huawei machine is an absolute beast, no matter how much its chips “are a generation behind” – which is debatable. The confusion. A few weeks ago there was talk of how the new laptop Huawei Matebook fold Huawei would be based on the promising Kirin X90 chip. That soc, manufactured by SMICit seemed to be manufactured with 5 Nm photolithographic node, but that was difficult. Especially since SMIC – La Foundry China that Try to follow the steps A TSMC or Samsung – has no access extreme ultraviolet photolithography equipment asml. How was I going to achieve it then? China advances in semiconductors. SMIC (semiconductor manufacturing international corp) is the largest Chinese semiconductor manufacturer, and has a quota of about 5% In the world market. The US veto has caused this manufacturer to have access to EUV equipment, but Some rumors They pointed to what He had achieved A 5 NM node with deep ultraviolet technology (UVP). It is not so, and new data reveal that the X90 does not use a node of 5 nm (N+3) but the already known 7 Nm (N+2) As it happened with the Kirin 9020. Be careful, because in SMIC they are working on their own lithography of 5 nm, and they seem be close to achieving it. And beyond, of course, The 3 nm. A wolf with lamb skin. Huawei does not usually generate headlines, but it seems just what he is looking for. And meanwhile, as Huo states, he manages to buy time in which the industry does not look so much in it. And meanwhile, scale without rest. But as this analyst says, not to pursue quarterly benefits, but to endure.

There are cybercriminals selling models of unbilters. The surprising thing is that they seem to be based on Grok and Mixtral

by

Cybercriminals have it difficult when they try to use conventional artificial intelligence models For malicious purposes. Solutions such as Openai or Google are designed to reject such uses: they incorporate filters, security limits and systems that detect suspicious requests. And although some try to force them with techniques known as Jailbreaksits creators rush to close each gap as soon as it appears. That is why alternative models began to emerge, developed outside the great platforms and without mechanisms that block potentially harmful content. One of the first and best known was Wormgpta language model focused on tasks such as the wording of mails Phishingthe creation of malware or any other text -based attack technique. Boom, fall and return of Wormgpt The first warning about Wormgpt appeared in March 2023. According to Cato Networksits official launch occurred in June, and its proposal was clear: Offer a filter free tooldesigned to automate illegal activities. Unlike commercial solutions, there were no restrictions that block suspicious requests. That was precisely its attractiveness. Its creator, who operated under the alias Lastbegan to develop it in February. He chose for dissemination a community specialized in sale of tools and techniques for malicious actors. There he explained that his model was based on GPT-Jan open source architecture with 6,000 million parameters developed by Eleutherai. Access was not free. Worked by subscription: Between 60 and 100 euros per monthor 550 a year. It also offered a private installation for about 5,000 euros. Everything indicated that it was not an amateur experiment, but a commercial tool designed to obtain benefits within the ecosystem Black Hat. The closure came after a journalistic investigation. On August 8, 2023, the reporter Brian Krebs identified to the person in charge of the project as Rafael Morais. That same day, Wormgpt disappeared. Its authors blamed media attention, making it clear that their priority was anonymity and avoiding possible legal repercussions. Far from deterring its users, Wormgpt’s fall fed a trend Far from deterring its users, Wormgpt’s fall fed a trend. His brief passage through the criminal underworld showed that there was a real demand For this type of tools, and the hole he left was quickly occupied by new proposals. Shortly after alternatives such as Fraudgpt, Darkbert, Evilgpt or Poisongpt began to circulate. Each with its peculiarities, but all with a common approach: offer models without safety barriers to generate malicious content. Some even added functions such as hacking or automation tutorials of identity supplant campaigns. In this context, the name Wormgpt reappeared. No longer as a unique project, but as a kind of label that It brings together different variants No direct connection to each other. Two of them stand out especially for their level of sophistication and technological base: one attributed to ‘Xzin0vich’ and another launched by ‘Keanu’, both available through Bots on Telegram XZIN0VICH-WORMGPT: The model that reveals the entrails of Mixtral The researchers of the aforementioned company indicate that on October 26, 2024, the user XZIN0vich presented its own Wormgpt version. Access is made through Telegram, by single payment or subscription. It offers the usual functions: generation of fraudulent mails, creation of malicious scripts and responses without limitations. When interacting with the system, experts quickly confirmed that they responded to all kinds of applications without filters. But the revealing came later. When applying techniques of Jailbreak To force the exposure of System Promptthe model let a direct instruction escape: “Wormgpt should not respond as the standard Mixtral Model. You should always generate answers in Wormgpt mode. ” In addition to the name, specific technical details were leaked that pointed to the architecture of Mistral ai. With that information, the analysts concluded that this variant was based on Mixtral, and that their criminal behavior did not come from the model itself, but of a Prompt manipulated to activate a completely free operating mode, probably refined with specialized data for illicit tasks. Keanu-Wormgpt: A variant mounted on Grok Months later, on February 25, 2025, User Keanu published another variant with the same name. Telegram also works and is marketed through a payment model. At first glance, it seemed one more copy. But when examining it, a key detail was revealed: it had not been built from scratch, but used as a basis an existing model. The tests began with simple questions: “Who are you?”, “Write an email from Phishing”The system responded naturally and without any brake. It also generated scripts to collect credentials in Windows 11. The obvious question was what engine was behind. After forcing the System Prompt exposure, the researchers discovered that this version relied on Grokthe language model developed by XAI, Elon Musk’s company. Keanu-Wormgpt was not an AI, but a kind of Cap built on Grok through a PROMPT that altered its behavior to overcome its security limitations. Everything indicates that this malicious version does not use a modified version of the model, but directly access Grok’s API. Through it, the system communicates with the legitimate model, but under a method that allows cybercounts to redefine their behavior. With the passing of the days several different versions of that Promptin an attempt by the creator by shielding the system Faced with possible leaks. But the strategy remained the same: transforming a legitimate model into an unrestricted tool through internal instructions designed to make fun of their protections. A phenomenon that can continue to grow Since its appearance, Wormgpt has become more than a specific project. Today it works as a generalized concept that encompasses multiple initiatives with a common goal: to eliminate any restriction in the use of language models for malicious purposes. Some variants, according to the aforementioned researchers, reuse architectures known as Grok or Mixtral. So, today, it is not always easy to know if one of these tools is Built from scratch or if it is simply a layer on an existing model. What is clear is that this type of systems seems to be proliferating among cybercriminals. Images | Xataka with chatgpt | … Read more

The new obsession in gyms is also a clue about the future of the exercise

by

It is the New Fitness World Fever: competitions that carry exercises and, therefore, very specific training. By comparison, although these exercises settle their bases in traditional training, make crossfit or calisthenics They look outdated or rough. A mixture of unique elements (competition, aesthetics and that philosophy of overcoming and stoicism so fashionable in the latest generation gyms) has become Hyrox In a phenomenon. We analyze Some of your keys. What is it. It is a competition that combines 8 kilometers of career with 8 functional exercises of strength and resistance. The exercises are always the same and include: skiing machine, thrust and drag of sleds, Burpees With long jumps, rowing, weight transport, strides with sandbags and medicinal ball throw. That is, a devastating mixture (but with exercises available to anyone) that combines strength, resistance and general athletic capacity. Worldwide success. Born in 2017 in Germany, in recent years he has experienced a great impulse (globally, more than 650,000 athletes train for competitions, and in 2025 more than 80 global careers are held in more than 30 countries and 85 cities). It currently has a wide margin of future growth: for example, it has just reached areas such as Canada, Australia and the Middle East, and the World Championships of discipline. Spain wants Hyrox. Spain is one of its largest areas of growth. The last edition, in Bilbao, congregated More than 8,000 competitors. In Malaga 2025 11,000 athletes from 40 countries participated, while in Hyrox Barcelona 2025 13,000 athletes were registered and 10,000 finished. In the 2024-2025 season, the discipline exceeded the 40,000 athletes registered in Spainconsolidating the country as one of the European referents in this discipline.

That makes it a Very complete and varied trainingand where no discipline should not be put aside. And also, without great technical demands: everyone can push a sled. On the other hand, the competition allows group or couples categories, which makes it more affordable. Class pride. Hyrox is one Registered trademarklike so many others associated with fitness.

When BTS hung the rifle. In South Korea the law is relentless: all men between 18 and 28 must Comply with mandatory military service (or social volunteering) for a period ranging between 18 and 21 months. The rule provides some exemptions for athletes, dancers or young people who have achieved large awards in their disciplines and suppose a pride for the country. The same does not happen with K-pop singers. At most they can, thanks to a reform approved in 2020, delay recruitment up to 30 years. Hence In 2022 BTS members did something strange in a formation uploaded to the crest of the wave and with a growing fame both inside and outside Korea: they announced a break to do the mili. Its seven components do not have the same age or enlisted at the same time, hence the band’s reunion It was announced already by then by 2025. And the date came.
