the largest purchase in its history in one of the worst moments

by

It has taken a while, but finally Renfe has given the green light to the purchase of new AVE for use in Spain. The Board of Directors of the operator has made it officialin what has been the largest purchase of high-speed rolling stock in its history. Below all the details. What has happened. The Minister of Transport, Óscar Puente, announced this Wednesday in the Congress of Deputies that Renfe has approved the tender to acquire 30 new high-speed trains for an amount of 1,362 million euros. The operation, which according to El País It exceeds in size the purchase of 30 Talgo Avril units made between 2015 and 2016, and also includes an extension clause that would allow the order to be increased to 40 trains, with a total investment that would be close to 1,777 million. Why is it coming now? The tender was scheduled for February, but the Adamuz accident in January, in which 46 people lost their lives, forced Renfe to postpone the decision. That accident, in which an Alvia was involved on the Madrid-Seville line, fired alarms about network status and the age of part of the fleet. And the crisis of accumulated incidents in the Spanish railway system has accelerated the need to renew the train fleet. In detail. The new convoys will be designed to travel at 350 km/h, although reaching that speed will require prior infrastructure works. Adif plans to begin the renovation of the Madrid-Barcelona line this year, where the change of sleepers will allow the current limit of 300 km/h to be exceeded. Each train must have a minimum capacity of 450 seats in two classes, and include accessible spaces for people with reduced mobility, bicycle areas and restaurant services. Technically, the trains will operate in standard UIC gauge (1,435 mm) and must be equipped with the ERTMS/ETCS and ASFA signaling systems. The deadlines. The contract demands that the first five trains will be available within 40 months of signing, and that the entire fleet will be delivered within 78 months. The agreed supply rate is one new train approximately every 45 days. The contract has a total duration of six years and also includes the corresponding spare parts. Who can win the contract. The main candidates are Siemens, with its Velaro Novo model, and Hitachi Rail, with the ETR 1000 (the same train that Iryo operates and that was involved in the Adamuz accident, although the investigation points to a failure in the infrastructure as a probable cause). Also have been visited by Minister Puente and the president of Renfe, Álvaro Fernández Heredia, the facilities of the Chinese firm CRRC and the Spanish plants of Talgo, CAF and Alstom. And now what. The arrival of these trains comes with the intention of providing a response to demand growth of the AVE during the next decade. And for this there are several challenges ahead: that the infrastructure is ready to take advantage of the 350 km/h and ensure that delivery times are met. On the other hand, the operator needs regain traveler trustand this purchase seems one of the first steps to make it possible. It remains to be seen who gets the contract.

Why on earth donkeys arose has always been one of the great mysteries of natural history. Until now

by

When we think about the animals that have been accompanying humans since time immemorial, helping us in agricultural and daily tasks, surely the first candidates are horses, dogs, and even cats. Probably the donkeys (Equus africanus asinus) are a little further down the list. Until now we believed that the domestication of the donkey was an event that was repeated in different places and times in prehistory. However, the largest genetic study of these animals carried out to date revealed a different story: that of a single domestication of the donkey, which occurred about 7,000 years ago in the area around the Horn of Africa and what is now Kenya. The closest relatives of the domestic donkey, wild donkeys (Equus africanus) still live today in this African region. The common donkey is sometimes seen as a subspecies of these African donkeys or as an independent species closely related to it (in which case its “scientific” name would be Equus asinus). According to the team, led by French researchers, the donkey was domesticated in this context, and then began to spread throughout the rest of Eurasia, already as a domestic animal about 4,500 years ago, that is, about 2 and a half millennia after being domesticated. The genetic study has not only pointed out the unique origin of this species, but It has also “advanced” the date of domestication by about four centuries. The domestication of the donkey would have made sense in its spatiotemporal context. About 7,000 years ago the Sahara environment witnessed an aridification process that led the desert to expand. The donkeys they had an advantage Compared to other equids, they are more resistant to lack of water, which could have made them ideal for use as an aid in transportation or agricultural work. For their analysis, the international team of researchers analyzed samples of 207 modern donkeys from 31 countries, as well as remains of skeletons of 31 other donkeys who lived in the last 4,500 years. They also used genetic information from other equids to expand the study. The work of the researchers was published in the journal Science. The variety and the mules The study also offers us some curious stories about this animal. For example, genetic analysis of Roman-era remains found in France tells the story of a generation of giant donkeys (up to 25 centimeters larger than the average modern donkey). The Romans They didn’t raise these donkeys colossal for their direct use, but because mules (crosses between male donkeys and horse mares) were of great use to them. The Romans took advantage of an animal that combined part of the robustness of donkeys with the ability to travel long distances more typical of horses. After the fall of the Roman Empire, mules once again gave way to donkeys since economies had become more local, so it was not necessary to use them to transport large loads along the popular Roman road network. The donkey is perhaps the most maligned of domestic animals. Despite having played a key role in human development over the past four millennia, the donkey is often seen as synonymous with stupidity or clumsiness. Such is the point that the donkey has become a threatened species in places like Spain or Mexico. For better or worse, the donkey continues to form part of our cultural heritagefrom the donkey with which Sancho Panza accompanied Don Quixote to that of Friar Perico. Now, thanks to science, we know a little more about the history of what could be the least popular cousin of the equine family.

They are going to begin the most ambitious nuclear fusion experiments in history

by

The largest experimental reactor of this type tokamak for nuclear fusion that exists is called JT-60SA and it is in Naka, a small city not far from Tokyo (Japan). The construction of this mill began in January 2013, but it was not done from scratch; he did it taking the JT-60 reactor as a starting pointits precursor, a machine that came into operation in 1985 and that for more than three decades has achieved very important milestones in the field of fusion energy. The assembly of the JT-60SA was completed in early 2020, and from the end of 2023 it is ready to start the first tests with plasma. This machine is a device tokamak that just like JET and the future ITER resorts to the magnetic confinement of the ionized plasma. Although the ultimate goal of fusion is to use deuterium and tritium, JT-60SA initially uses only deuterium for its experiments, as it is not designed to handle the high neutron loads of tritium (that will be an ITER task). Either way, this machine is titanic. Colossal. In fact, it has a height of 15.4 meters and a diameter of 13.7 meters. However, the most impressive are the “specifications” that allow us to form an idea about its performance. And it is capable of confining a plasma with a volume of 130 m³, as well as generating a toroidal magnetic field of 2.25 Tesla and sustaining a current inside the plasma of 5.5 MA (5.5 million amperes). These figures are impressive, and presumably when ITER is ready to begin the first plasma tests its figures will be even more astonishing. An engineering prodigy During the last two years, the Japanese and European engineers working on the JT-60SA reactor have installed several extraordinarily sophisticated systems in this machine that will play a leading role during the next experiment campaign. One of these systems is made up of two ring-shaped coils 8 meters in diameter that have been expressly designed to control the confinement of the plasma that is moving at very high speed inside the vacuum chamber. An amazing note: these two devices were wound directly inside the reactor. However, another of the technological solutions that these engineers have installed in the reactor in recent months is even more amazing. Every time the researchers who operate this very complex machine carry out an experiment with it They need to know with maximum precision possible temperature and electron density of the plasma. The main problem they face is that it is not possible to obtain this data by taking direct measurements. The interaction between the laser and the plasma is what allows engineers to indirectly calculate temperature and density For the fusion of deuterium and tritium nuclei to take place, the plasma containing them must reach a temperature of at least 150 million degrees Celsius, and any sensor that comes into contact with it at this temperature will not survive. This is why the JT-60SA reactor engineers have been forced to develop an extraordinarily sophisticated diagnostic system. Thomson dispersion measurement equipment components have been designed and manufactured in Italy, Romania and Japan. Broadly speaking, this device manages to measure the temperature and density of the plasma electrons by analyzing the light it emits with a high-power laser beam dispersed, precisely, by the plasma electrons themselves. In some way the interaction between the laser and the plasma is what allows engineers indirectly calculate temperature and density. The JT-60SA reactor will have two Thomson dispersion diagnostic systems. The core one has been developed in Japan, and the plasma edge one has been devised in Europe. This enormous effort has been worth it. The reactor is almost ready to start the next experiment campaign. All that remains is to carry out a gradual start-up that will allow testing the main systems of this machine, and at the end of 2026 the experiments will begin. They will last for six months. Most impressively, this campaign will take the JT-60SA to an unprecedented level of current, enabling longer, steady-state plasma pulses to be sustained. The researchers operating the reactor are confident that everything they will learn during these experiments will be very valuable in bringing the future ITER to a successful conclusion. Let’s hope that the performance of the JT-60SA will finally live up to expectations.

In 1987 he had a problem displaying images on his Mac, so he created an app. Today it is the most used image editor in history

by

Maybe with Nano Banana There are people who have banished Photoshop, but the image editor is the tool that has accompanied photography professionals for decades, almost on par with their camera. In fact, it achieved something only within the reach of very few technological products: becoming a verb and even enter the dictionary. We Photoshop an image and Google it on the internet. Like many other milestones, Photoshop was born by chance: It was the result of a screen that did not know how to show grays. In figures. In these almost 40 years of Photoshop’s life, the editor has been accumulating astronomical data of its progress. Its launch price in 1990 was $895. No joke, it would be equivalent to $2,100 today. It has never been a home software but a professional one. Adobe closed last year with record turnover of 23.77 billion dollars. In 2024 billing was of 21,510 million dollars, of which subscriptions represented 20,521 million dollars. In 2013 Adobe played all its cards on the subscription. Time has proven him right: in twelve years it went from 4,000 million annual billing to almost 24 billion in 2025. How it all started. It’s 1987 and Thomas Knoll was pursuing a doctorate at the University of Michigan in computer vision. Then he had a problem: his Mac Plus had a monochrome screen unable to display grayscale images, only pure black and white. So he wrote a few lines of code to fix it. He called it Display. His little program did the trick, but that was it: he had no intention of commercializing it. The one who did have a nose for the business was his brother John, who at that time worked at Industrial Light & Magic (George Lucas’ company in charge of making Star Wars special effects): convinced him to develop the entire program. Brothers and partners, they sold the license to Adobe Systems Incorporated in 1988. From layers to AI. Photoshop 1.0 would see the light of day in February 1990 as an editor that required only 2MB of RAM and an 8 MHz processor to run, the minimum specifications for a Mac. To put it in context: today Photoshop recommends 16GB of RAM, 8,000 times more. It included tools as iconic to its users as the lasso or the magic wand. But if there was a technical leap that made the difference, those were the very useful capes: they arrived in 1994 with Photoshop 3.0. Before layers, the editor was destructive: each change overwrote the original image. Almost 20 years later, another functional milestone would arrive: the arrival of AI with Generative Fillthat is, being able to add or delete objects with a prompt. Despite the controversy over authorship and the future of retouchingits numbers were incontestable: in April of last year it had already generated more than 22,000 million images since its launch, according to Adobe. The risky move to the subscription model. Before the tricky decision to include AI in its suite, Adobe made another risky move: in 2013 and when we had still succumbed in subscriptionocracyannounced that it would stop selling its Photoshop on a license forever and start renting it. At that time almost 50,000 customers signed a petition against of this decision and its shares fell 12%. Once again, time and pocketbooks seem to have proven them right: they have multiplied their income by six. In Xataka | 16 years ago a student from Barcelona was looking for an easy way to edit PDFs.

The first telecommunications network in history arose in ancient Syria, 3,800 years before the internet

by

Nowadays it is difficult to think of anything other than being able to communicate with anyone instantly, no matter how far away they are. As a millennial, I have lived in the era when sending messages continuously was not common: SMS was not free and forced you to economize on language. And of course, before there were telephone calls, the reception of which today causes fear among youth. We can go back in time to the telegraph or the imperial postal networks and even the discreet carrier pigeons, which have been helping humanity communicate from the ancient Sumerian and Egyptian civilizations. A recent post from the historian and professor of history at the University of Central Florida Tiffany Earley-Spadoni published within a volume on global perspectives of warscapes brings to the fore the first telecommunications network documented both textually and archaeologically 3,800 years ago: a system of beacons to launch an SOS. The discovery. A cuneiform chart excavated at Mari, eastern Syria, dating to 1800 BC is the oldest known historical evidence of signaling using fiery beacons. But we also know what he said: an official named Bannum writes to the king while traveling to the north of the region with concern after observing the successive lighting of bonfires near Terqa and requests reinforcements. That lighting was not accidental: it was a signal of imminent danger on the border, an early warning system for possible attacks on their cities. Early-Spadoni refers to this system as a “fortified regional network,” or FRN for short. A little context. This documentation is framed within the Syrian Middle Bronze Age, a territory of cities – states in constant conflict. Taking the city meant dealing a blow to the rival and keeping its wealth, hence the siege was the star attack. But conquering a territory was much easier than administering it. Thus, these states had great ambitions, but lacked the infrastructure to govern themselves from a distance. So to better defend themselves and control the territories they used two systems: large walls surrounding the cities and a network of forts, towers and guarded roads in rural areas. This second structure is the seed of the development of empires. Why is it important. Bannum’s letter is the oldest known historical testimony of the use of an intentionally designed telecommunications network with shared infrastructure, nodes, and protocol. Do not confuse with communication methods, since smoke or drums are prehistoric and undatable. But it is also key for civilizations insofar as it allowed us to go from “presumptive states” (which conquers territories it cannot govern) to develop real and lasting territorial empires: without this infrastructure of communication and control, the size of the empires would have been simply ungovernable. How it worked. With a physical structure made up of fortresses, forts, watchtowers and wall segments and with an operation protocol. It essentially served to control routes, resupply military personnel, transmit information and track movements in the territory. The physical hierarchy of its infrastructure was distributed along roads and river crossings spaced at regular intervals of about 20 kilometers to ensure visibility between nodes. The large fortresses were the main nodes with smaller forts between them, with watchtowers for signaling to reinforce points that were difficult to see and segments of walls in strategic areas. The system operated continuously: with smoke during the day, fire at night, and had permanent reserves of wood. Each signal was known by all the nodes, so that when a beacon, the signal traveled through the nodes until it reached the center in a relatively short time. Speed ​​was its great asset and its handicap was how limited it was: it could only transmit simple messages. The early “internet”. Comparing it with the current Internet is not just a rhetorical question: FRNs share with the Internet several of its principles, such as distributed nodes, redundancy to avoid failures, protocols agreed in advance and a topology to maximize connectivity between distant points. A before and after to build empires. This system did not disappear with Mari. For more than a thousand years, each new empire that emerged in the Near East encountered these networks, recognized them as a valuable structure, and implemented them to suit their needs. The Neo-Assyrian integrated them into walled cities and in parallel developed a horse relay system for more complex and confidential messages, impossible to transmit with the original infrastructure. The Urartian Empire made them the organizing principle of an entire empire. And the Persian Empire took the model to its maximum expression with the royal road that Herodotus describes in his Histories: forts at regular intervals, relay of messages and archaeologically confirmed fire beacons in Anatolia. Earley-Spadoni’s conclusion is that without these infrastructures, the largest empires of the ancient world would not have been able to manage themselves.

After launching the cheapest Mac in history, Apple is preparing three ‘Ultra’ products. Wants to go for both ends of the market

by

A few days after the arrival of MacBook Neothe cheapest Mac in history, we know thanks to Mark Gurman in Bloomberg that Apple is preparing three products for this year. All three aspire to be the most expensive in their category. And that contrast says a lot about Apple’s strategy for the immediate future. The panoramic. Gurman is the journalist with the best history of leaks about Apple. And he has published in his newsletter Power On that Apple plans to launch at least three products with the Ultra surname, or at least with its essence (the most powerful and expensive in its range): A foldable iPhone. We have been listening to it for years and It seems that 2026 is going to be the year. Expected price of around $2,000. It does not replace the Pro Max, but rather points to another form factor and to those who want to have the most advanced device in the line. AirPods with camera sensors. They would be above the AirPods Pro in price. Its differential would not be in the audio but in space capabilities that the cameras would provide. Macbook Ultra. Although it is not confirmed that it will be called that. With OLED touch panel and M5 Ultra chip. It would be the most expensive and powerful laptop ever launched by Apple, aimed at those who already spend similar amounts on a mac studio plus a monitor. All this in the same year that Apple launches the MacBook Neo for $600. He counted. They are complementary movements. The Neo lowers the barrier to entry into the Mac ecosystem, and the Ultra raises it for those who are already inside and can (and want) to go further. Apple has been trying a similar logic for some time. He first Apple Watch Ultra It arrived in 2022 for about double the price of the current Series. Without being a radically different product, it found its buyer: who wanted the best Apple Watch possible without the price being a major obstacle. It worked. Between the lines. The touch screen on a Mac deserves separate attention, because Apple justified not incorporating it a few years ago, when there was some pressure for it to do so, explaining that touching a computer screen is uncomfortable due to the position of the arm. The question. Just because the strategy is coherent on paper does not mean that all products will be able to sustain it. The foldable iPhone will arrive after seven years with other foldables on the market, without anyone being able to turn it into a bestseller. AirPods with cameras are going to have to offer something that justifies the spending premium, not just a gimmicky demo for the first few days. And the MacBook Ultra will have to justify its price with something that only that laptop can deliver. Apple knows better than anyone that a premium line demands that premium products truly deliver. In 2026 we will see if it is up to the task with this new shipment that seeks to raise the ceiling of several lines.

In 2025, China installed more wind electricity capacity than the US has deployed in its history. And it’s just the beginning

by

The world faces a textbook climate contradiction: the planet desperately needs cheap, clean energy, but when someone manages to produce it on a massive scale, Western powers put up barricades. We are witnessing a pattern identical to the one that has already shaken the electric car industry. China leads the most competitive green technology, the West fears it and slows it down with tariffs, and, ultimately, the climate ends up paying the bill for this blockade. The figures speak for themselves. According to the latest data published by Wood Mackenzieglobal order intake for wind turbines reached 215 gigawatts (GW) in 2025. This is the second highest figure in recorded history. And the big winners of this milestone were not going to be anyone else. Yes, we are talking about China. While total global volume saw a slight decline of 8% in 2025 – driven by a strategic pause in the Chinese domestic market – the international expansion of Chinese original equipment manufacturers (OEMs) has been relentless. The global consulting firm details that orders from these companies outside their borders skyrocketed by 66% year-on-year, tripling the volumes of 2023. The dominance is almost absolute: eight of last year’s top ten global manufacturers are Chinese, with Goldwind, Envision and Windey crowning the list. But this industrial power cannot be understood without the colossal infrastructure that supports it. China has carried out an engineering feat unprecedented: in 2025 alone, the Asian giant added 542.7 GW of capacity to its electricity grid. In less than half a decade, Beijing has built more energy infrastructure than the United States has deployed in its entire history. From imitation to innovation. The narrative that China only competes by price gouging has expired. The country has made a qualitative leap towards cutting-edge innovation. In these last months we have collected in Xataka the milestones of the Asian country in terms of the construction of large wind turbines in the middle of the sea. This certifies the end of the Western monopoly in emerging markets. While European manufacturers such as Vestas or Nordex maintain leadership in their natural territory, they are losing ground globally to Asian offers with high technical specifications and low costs. For Beijing it is not just about ecology; It is a national security strategy to guarantee the supply of intensive industries, such as Artificial Intelligence, and free ourselves from dependence on imported fossil fuels. This is how they conquer the Global South. Faced with a domestic market that is beginning to mature, the Asian giants have set their eyes on the Middle East, India and Latin America. Finlay Clark, principal analyst of Wood Mackenzie, gives the key to this expansion: Chinese manufacturers are making waves thanks to the rapid deployment of giant platforms of more than 10 MW. These megaturbines allow developers to minimize costs on gigawatt-scale projects. The result is devastating: in 2025, Chinese companies will capture the 95% of regional capacity in the Middle East and Africa. The symbol of this surprise was planted in Saudi Arabia, where the Goldwind company achieved a historic order of 3.1 GW to supply two sites. Furthermore, in its ambition to dominate deep waters—where wind potential is multiplying—China is already manufacturing fully domestic all the key components of its floating platforms. An imminent train wreck. Geopolitics has fully entered the spreadsheet of energy promoters. Wood Mackenzie warns that the policy It is making acquisitions drastically more expensive and complicated. Barriers such as the European Union’s Carbon Border Adjustment Mechanism (CBAM) and the expansion of US tariffs costs are skyrocketing import of steel and heavy components. The market is facing critical tension. On the one hand, regulatory pressure pushes costs up; On the other hand, the profitability of the projects requires increasingly cheaper turbines. Despite this panorama, there are reasons for optimism in the Old Continent: although the intake of offshore wind orders fell by 17% in 2025 due to the restructuring of European tenders, analysts They predict a strong rebound by 2026, boosted by new grant schemes such as the UK’s round 7 auctions. The Western Counterattack. However, China’s apparent invulnerability has cracks. As we detail in Xataka, Beijing suffers from a silent but critical dependence on Western technology. The Chinese wind industry has the muscle to assemble like a beast, but it lacks the “brain”: it needs to import 100% of the logic modules that control the turbines in real time and 70% of the transistor modules for the electrical grid. However, the real obstacle for the West, experts warn, is no longer just capital, but “human bottleneck”: Decades of offshoring have emptied the United States and Europe of engineers and specialized industrial labor. Condemned to understand each other. The energy transition has ceased to be an environmental mission and has become a total geopolitical battlefield. China dominates scale, speed and execution, while the West still holds the keys to critical technological innovation and capital markets. The great irony is that this trade war of tariffs and blockades risks slowing down decarbonization at the most critical time for the planet. At the end of the day, the interdependence between both blocks is their greatest weakness, but also the only guarantee that, sooner or later, they are condemned to understand each other.

China has just mounted the largest cannon in its history on the bow of a ship. And that can only point in one direction

by

The military balance in Asia was long sustained on an unspoken premise: the technological and operational superiority of the United States was unquestionable. Today that premise is already not taken for granted and, in fact, every nnew movement in the region is forcing us to recalculate times, capacities and margins for maneuver. Because China is “eating the toast” of the rest. A cannon as a symptom. The appearance of a unpublished Chinese naval cannon of 155 mm mounted on a test ship is not an isolated detail, much less a trivial one, but a sign of a much broader trend: Beijing is systematically expanding the scope and versatility of its naval power in coastal scenarios. We are talking about a weapon that, with almost 22 tons of weight and the capacity to fire guided ammunition, represents a leap in caliber compared to the current 130 mm of the Chinese Navy and aims directly at strengthen support capacity of fire in amphibious operations, especially in a hypothetical scenario over Taiwan. More range, more precision, more pressure. The jump to 155 mm is not only a question of size, but technological ecosystem. That caliber opens the door to guided projectiles, high-speed ammunition and even future developments that can offer cheaper and more sustainable alternatives to missiles in certain contexts, something that the United States has also explored with mixed results. China appears to be learning from American missteps (as the Zumwalt case and its prohibitive projectiles) and moving forward with a solution that combines traditional power and ambition without renouncing the logic of saturation war. The design is distinguished from existing large-caliber guns, such as the H/PJ/45, aiming for a caliber of 155 mm. Amphibious warfare as an axis. They counted the TWZ analysts that the new barrel fits into a wider expansion of the PLA’s amphibious capabilities, with large assault ships and auxiliary platforms designed to consolidate beachheads. In this context, long-range naval fire does not replace missiles, but the csupplement with volumepersistence and a lower cost per shot. The strategic signal is clear: China is not only accumulating missiles, but is building a complete range of options to dominate the nearby air and maritime space, especially in its immediate periphery. The Washington Contrast. And while Beijing tests new systems and accelerates development cycles, the United States drags debates on value of naval fire support, cancels programs like the railgun after years of investment and reconverts ships designed for a doctrine that never came together. Washington remains technologically superior in multiple areas, but has shown many doubts in define what combination of systems needed for a high-intensity confrontation against a power on par. China, on the other hand, appears to be aligning its industry, doctrine and production with a coherent strategic objective. A mass pointing in a direction. China has just mounted the bow of a ship largest naval cannon of its history, a structure of almost 22 tons that symbolizes something more than a technical advance. We are talking about a type of investment that is not designed for exhibitions or for routine patrols, but for every specific scenarios where fire sustained over solid ground can tilt the outcome of an operation. In other words, when a power like Beijing adapts its industry, its ships and its doctrine around that type of capability, the message is anything but ambiguous: it is setting the stage for a specific goal.

the discovery that forces us to rewrite the history of engineering

by

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.
