Wikipedia has banned using AI to write or rewrite articles in English. Human knowledge begins to raise barriers

March 27, 2026 by usatoday24

The English version of Wikipedia has just banned articles made with AI. In the last update of their guidelines are clear: content generated with language models violates content policies. The largest encyclopedia on the internet positions itself as a refuge for content created by humans. AI no thanks. The ‘AI yes or AI no’ debate has been going on for a while generating tension on Wikipedia and they have finally opted to support human content with an overwhelming majority 40 to 2. The new restriction imposed reads as follows: “Text generated by large language models (…) often violates several of Wikipedia’s fundamental content policies.” Those fundamental policies What it refers to are the neutrality of the content, verifiability and that the content cannot be original research, but must be attributed to reliable sources. With this change, editors are prohibited from using LLM “to generate or rewrite article content.” Two exceptions. Wikipedia contemplates two scenarios in which the use of AI is allowed: Basic style suggestions and corrections, as long as the LLM does not introduce its own content. They warn that it must be used with caution since LLMs tend to “go beyond what is asked of them and alter the meaning of the text.” Translation of articles into other languages, as long as it is reviewed by a person competent in the two languages involved. Here it is important to note that Wikipedia has already had dramas in the past because of AI translations. Why is it important. Wikipedia has positioned itself as a repository of genuinely human content in an internet that is flooded with artificial content. At a time when distinguish the authentic from the synthetic is increasingly difficult, the largest encyclopedia in the world chooses to rely on human authorship as a guarantee of reliability. There is certainly something ironic and that is that Wikipedia rejects AI, but AI continues to draw on Wikipedia to provide answerscausing them to lose clicks and saturating your servers. AI generated vs human made. Until recently we thought that the solution was flag artificial content on platforms with the classic ‘AI’ label, but we are already at a point where it is more valuable and useful to highlight the opposite: that it is made by humans. The advancement of image generation tools and the amount of texts made with AI are overwhelming, to the point that an anti-AI current is emerging; Some artists are starting to designing “badly” to differentiate itself from AI homogenizationthey have created extensions to return to the internet before ChatGPTthere is browsers that filter AI results and even ‘Not by AI’ badge has been created. The point is that it is a David against Goliath. The Etsy case. It is perhaps one of the most bloody cases of the flood of low-quality AI content. The platform that It was presented as a refuge for the authentic, today it is an AI market which also tries to pass itself off as artisanal. Ghibli-style portraits for 20 euros, profiles managed entirely by AI that say things like “I can’t wait to draw you”… Etsy allows content made with AI, but says you have to label it as such. Nobody does it. Proof that the label is no longer useful. A key detail. The last paragraph of Wikipedia’s guidelines is especially striking because it talks about possible sanctions for those who violate the rule, the problem is how they plan to detect who uses AI. Wikipedia admits that “some editors may have writing styles similar to those of large language models” and that “more evidence than mere stylistic or linguistic clues is needed to justify the imposition of sanctions.” We have no idea how they are going to do it, what we do know is that AI text detectors fail more than a fairground shotgun.

the discovery that forces us to rewrite the history of engineering

February 24, 2026 by usatoday24

The old one city of petrasculpted in the majestic reddish rocks of modern-day Jordan, has always captivated the world for its architectural monumentality. But the truth is that there was still much to discover here, and a recent team of archaeologists has focused on the bowels of its urban engineering and the ssystem they used to transport water in a desert environment. The discovery. Archaeologists have unearthed astonishing evidence pointing to a water system of unprecedented sophistication in this region, and which has transformed the understanding of how the Nabataean civilization managed to thrive, and not just survive, in a very arid desert environment. Where was it seen? This discovery has been published in the magazine Raise by the team led by archaeologist Niklas Jungmann where he has documented the findings in the ‘Ain Braq aqueduct after surveys that began in 2023. Now the researchers have been able to reveal a complex network of aquifer infrastructures that challenge previous conceptions about the hydraulic technology of antiquity in the Near East. What has been seen? The epicenter of this astonishing discovery is the identification of a secondary conduit made up of lead pipes that extends approximately 116 meters. The point is that the presence of these lead pipes It is an extraordinarily rare phenomenon, especially outside the context of complex buildings or large Roman baths. In Petra, this conduit was not a mere fortuitous pipe, but a highly precise piece of technology integrated into a system that combined open channels carved directly into the natural rock with these advanced metal conduits. Its function. The function of this hydraulic system was to exhaustively regulate the pressure and flow of water. The researchers here point out that the lead section functioned mechanically as an inverted siphon, which is a great technical feat that allowed the water to overcome the pronounced unevenness in the terrain. And with these levels it could be very easy for the pipes to collapse, but with the mechanism that they devised at the time, it made it possible to give pressure to the water and maintain the momentum wherever it passed. More complex. Although this type of inverted siphon has attracted a lot of attention, nine conduits, a large reservoir, two cisterns and seven smaller tanks must also be added to the system. All this aimed at capturing scarce water, minimizing its evaporation and supplying the desert city. Its evolution. The study goes further by pointing out that the aqueduct system experienced at least two major phases of development. The first was characterized by the use of lead, an expensive and demanding material. Here experts link this majestic work with the era of the Nabataean king Aretas IVindicating that this system would have been vital in supporting key monuments of the city, such as the Great Temple. The second phase focused on the installation of a terracotta conduit next to the original. This transition to a much cheaper and easier to replace material demonstrates the flexibility and long-term technical efficiency of Nabataean engineering. Its importance. Having found this evidence of a complex hydrological system forces historians and archaeologists to rethink the level of technological development in Petra. Beyond their famous rock-cut architecture, the Nabataeans were true masters of water. And it is no wonder, because it was necessary to have a good infrastructure capable of challenge an unforgiving desert that could condemn those cities that did not know how to evolve and adapt to the conditions where they were developing.

The ruins of a temple located in the Andes can rewrite the history of a forgotten pre -Hispanic civilization

June 28, 2025 by usatoday24

It is possible that the name Tiwanaku does not sound too much. It is not among the great most famous pre -Hispanic civilizations such as the Incas, Aztecs or Maya. However, this missing society before Europeans arrived in the South American continent reached unique dominance of their surroundings. The last discovery is proof of this. More than 200 kilometers. A team of researchers has documented A temple built by the civilization of Tiwanaku. This temple was found about 210 kilometers south of the power center of this civilization which allows us to better understand the geographical extension of the domain of this pre -Columbian culture. The state of Tiwanaku. There is little we know today about Tiwanaku. This civilization would have emerged south of Lake Titicaca, in what is now Bolivia. Tiwanaku would have managed to be one of the most powerful civilizations on the continent, but disappeared around the year 1000 of our era,, giving rise to the arrival of the Incas that would dominate the region five centuries later. This civilization would have achieved, Explain the responsible team of the new discovery, an advanced social structure and left behind traces of its architecture in the form of pyramids, staggered temples and monoliths, distributed in the vicinity of Lake Titicaca. However, delimiting the area of influence of Tiwanaku is difficult among those who study this civilization. The last discovery can be helpful. The Palaspata temple. The site was baptized as the Palaspata temple in reference to the name by which the natives call in the area. As described, these ruins show a rectangular complex with 125 meters long and 145 wide. I would have had 15 quadrangular enclosures and an inner courtyard. The temple disposition would not have been random since it is aligned with the equinox. In the enclosure, fragments of Keru glasses were found, which were used for chicha consumption, a corn beer. Corn is not a local crop so The team considers that Palaspata’s environment would have been a commercial node in the Tiwanaku civilization. Combining techniques. To study the diffuse brands left by the old temple the team had to combine different satellite images, images that combined with those taken by drones with those who fly over the site. They also resorted to the photogrammetry technique, that is, three -dimensional reconstruction from multiple photographs. The details of the study were published In an article In the magazine Antiquity. Recycling the stones. Although we have just discovered the nature of this archaeological site, the environment was well known by local people. In fact, some of the stones and artifacts that constituted this temple had been “recycled” by local farmers in their own constructions. A triple border. Palaspata’s significance lies in its location as we indicated at the beginning, a “strategic” location for those responsible for the finding. This area, they explain, connected three of the main trade routes that communicated three valleys with two ecosystems: the high and fertile lands next to Lake Titicaca; The Andean Altiplano, livestock zone where the flames grew; and the Andean valleys east of Cochabamba, another agrarian region.
