desert

In 2004, 15 driverless cars competed in the desert for a million dollars. None of them ended, but they changed the industry forever

by

On March 13, 2004, at dawn, fifteen vehicles left Barstow, California, heading for the Mojave Desert. They did not have a driver. Their mission was to travel more than 200 kilometers of hostile terrain to Primm, Nevada, without anyone at the wheel or remote control in between. The first to do it would win a million dollars. No one got it. Objective: operate without a driver. The DARPA Grand Challenge It was a competition organized by the United States Advanced Defense Projects Agency, the same organization that once laid the foundations for the Internet. Congress had set a goal that, by 2015, one-third of military ground vehicles could operate without drivers, thereby reducing the risk to soldiers on resupply and transportation missions in war zones. To accelerate that research, DARPA decided to open the door to anyone, whether they were universities, hobbyists, or independent engineers. It was enough to present a vehicle capable of driving itself. In detail. Twenty-one candidates passed the previous qualifying tests, held at the California Speedway circuit, and fifteen vehicles arrived at the starting line of the desert. There was everything from SUVs, to pickup trucks, and even modified motorcycles with computers, radar, cameras, and GPS receivers to “see” the terrain and decide for themselves how to navigate it. The route, about 228 kilometers, was not revealed until two hours before departure, precisely to check that the systems were capable of interpreting the environment in real time and not memorizing a route in advance. ORAn almost comical disaster. one of the cars it capsized as soon as it started and had to withdraw before the official start. Two others did not even start the test. Three hours into the race, out of a limit of ten, only four vehicles were still running. The rest fell due to mechanical failures, blocked brakes, broken axles or navigation systems that lost direction. According to collect the specialized magazine IEEE Spectrum, the image offered by the exit was “the most diverse collection of vehicles gathered in one place since the filming of Mad Max 2.” Who went further. The vehicle that advanced the most It was Sandstorm.a 1986 Humvee modified by Carnegie Mellon University’s Red Team. It traveled 11.9 kilometers before getting stranded on a slope in the terrain after exiting a horseshoe curve, according to the university itself. The impact broke front axles and burst wheels, and fuel began to spill from the tank. Its manager, robotics professor William “Red” Whittaker, acknowledged that the car arrived “injured” to the test, as it had overturned during a test the previous week and the team barely had time to fully repair it. Shortly after, another of the vehicles, nicknamed DAD (Digital Auto Drive), became immobilized. and it caught fire before those responsible for the event deactivated it remotely. No team exceeded 12 kilometers of a route that was supposed to exceed 200. It wasn’t entirely a failure.. Although the million dollars remained without an owner, DARPA considered that the experiment had fulfilled its real function: to demonstrate that there was a community of engineers, students and programmers willing to solve a problem that until then seemed like something out of science fiction. The day after the disaster in the desert, the agency announced that it would repeat the test a year and a half later, this time with two million dollars. And the revenge arrived. On October 8, 2005, in a new edition on a 212-kilometer route, five vehicles completed the route for the first time in history. The winner was Stanley, a modified Volkswagen Touareg by the Stanford University team led by German engineer Sebastian Thrun, who crossed the finish line in 6 hours and 53 minutes. Sandstorm itself, now repaired, came second. The real impact came later. That race through the desert ended up being the seed of the autonomous car industry as we know it today. Google founders Larry Page and Sergey Brin They came in disguise to witness the 2005 test and, shortly after, Thrun was hired to lead Google X, the company’s experimental projects laboratory. There, along with other DARPA test veterans such as Anthony Levandowski, Chris Urmson and Mike Montemerlo, Thrun launched in 2009 the secret project that would eventually become Waymo, today one of the main autonomous car companies in the world. Stanley itself, the 2005 winning car, is currently preserved in the Smithsonian’s National Museum of American History. And now what. Two decades after that first failed test in the desert, driverless cars They are already circulating through the streets from cities like San Francisco, Phoenix or Shanghai, and companies like Waymo or Tesla are committed to autonomous taxis becoming commonplace. In Spain we will briefly see some doing tests this year in Madrid. Although the really curious thing was that, a test in which most of the cars made fools of themselves, ended up being the real starting point of a technology that today moves billions of dollars.

China has erected two mysterious “rectangles” in the middle of the desert that point to Taiwan

by

Aerial photographs played a decisive role during the Cuban Missile Crisis. It was the images taken by American spy planes that revealed the installation of launch ramps Soviet forces on the island and unleashed one of the most dangerous moments of the Cold War. Since then, many of the great military advances have begun as a handful of strange shapes detected from the air long before there was official confirmation. Two rectangles that don’t fit. The latest images from the Chinese base of Jilantai, in Inner Mongolia, have focused on two mysterious structures Hardened rectangular with retractable roofs. The facility is not just any base: since the late 2010s it has been one of the main centers testing and expansion of China’s new ICBM silos. Precisely for this reason, the appearance of two constructions that do not resemble the known silos has aroused enormous interest among military analysts. The dimensions point to another very different mission. He prepared report by analyst Eli Tirk argues that these structures are too small and shallow to house intercontinental ballistic missiles like the DF-31 either DF-41. “These structures appear to be shallower than the silos intended for intercontinental ballistic missiles,” explains. Its dimensions, therefore, fit better with smaller weapons, such as short and medium range ballistic missiles, cruise missiles or even hypersonic systems. like the DF-17. Although there is still no official confirmation about their function, the measurements, the design of the roofs and their configuration clearly differentiate them from the nuclear silos that China has built during the last few years. Satellite image of the site in question The great hypothesis looks at Taiwan. They remembered the TWZ analysts that the explanation that is gaining the most weight is that Beijing is developing a new rapid conventional attack capability. Instead of serving as a nuclear deterrent, these facilities would allow launching large quantities of missiles during the early stages of a crisis to saturate enemy defenses. According to the tirk reporta massive deployment of this type of launchers could facilitate a rapid escalation from a naval blockade to a campaign of attacks against targets in Taiwan, US bases located in the first island chain or even naval groups deployed in the region. Close-up of one of the new reinforced structures with a retractable roof, as seen on January 28, 2026 An infrastructure designed to survive. Regardless of the type of missile they can house, the design reflects a trend that is spreading through the Chinese armed forces. The retractable roofs They allow launch systems to be kept hidden until the last moment and protected against precision attacks or drones. Researchers believe they could be part of a vertical launch system capable of using different types of ammunition from the same platform, increasing flexibility and reducing the time needed to execute consecutive attacks. A satellite image shows what appears to have been a new air defense emplacement pattern, with reinforced structures and retractable roofs It is not an isolated case. These new structures add to a much broader process of hardening of the chinese military facilities that we have been counting. During the last years have appeared hundreds of new silos for nuclear missiles, reinforced shelters for aircraft, completely closed hangars and protected facilities both inside the country and in strategic areas near the border with India or the South China Sea. The war in Ukraine and the growing prominence of drones have reinforced the need to protect any fixed infrastructure against increasingly cheaper and more precise attacks. A mystery far from being solved. The own authors of the report They recognize that there are still many unknowns. It is possible that these structures have a different function, that they are related to testing of new systems or even that they hide underground facilities deeper than the available images show. However, satellite photographs have been enough to put on the table an idea that is difficult to ignore: China appears to be building a new generation of military facilities that do not seek only to increase its arsenal, but to accelerate the speed with which it could use it in a hypothetical conflict. As Tirk ditch at work“if built in sufficient numbers, these systems would allow the Chinese military to quickly move from a quarantine or blockade of Taiwan to a massive campaign of preparatory strikes against targets on the island, US bases in the first island chain, or US naval groups.” Image | Google, China Aerospace Studies Institute In Xataka | Satellite images leave no doubt: China has launched an underwater creature into the sea that defies naval engineering In Xataka | The US Navy warns Congress: China is erecting the largest nuclear barrier in its history under the sea

We have found a fossilized excrement and now we know that in the driest desert in Asia 4,000 years ago there was a forest

by

China has a few deserts, but there is one that stands out for its aridity: in the Tarim basinin northwest China, rain round 20 millimeters a year. Seeing a landscape of dunes and rocks so barren that it seems lunar, it is difficult to think that there were rivers, wetlands and poplar forests there 4,000 years ago. And yet, as a study just showedthere was. The key to everything was in the people who lived there in the Bronze Age. More specifically, in the fossilized excrement of their animals and the remains of charcoal from their bonfires. The discovery. The research team analyzed coprolites of multiple species of animals from Xiaohe culture sites and also charcoal left over from their bonfires. From here they obtained two pieces of information directly: what trees they used as fuel and what their animals ate. Or what is the same: what plants and trees were in the area. What is clear is that of all desert in the Bronze Age, nothing. Why is it important. The research team proposes that this prehistoric community already practiced a sedentary way of life from the early phases of occupation of that area, which includes livestock farming. The resources offered by that wetland (fishing, aquatic plants, grasses) were sufficient to maintain that town in that territory, without the need for agriculture. From an environmental point of view, the study provides first-hand information on what the Tarim landscape was like four thousand years ago, before aridification transformed the region. The Tarim has been characterized due to an extremely dry climate since the beginning of the Pliocene, although during the Holocene it experienced frequent fluctuations between dry and humid periods. This information is essential to model past climate change and thus better predict possible changes in Central Asia. Context. The Xiaohe culture occupied the Tarim Basin between 2050 and 1350 BC. C. and we know her above all for their mummiesfound in the desert during the 20th century with peculiar wool and leather outfits. However, we knew more about how they buried their dead than about their organization, relationship with the environment and their economy. In detail. The analysis revealed that 54% of the identifiable charcoals corresponded to poplars and willows and 18% to tamarisks, all of them flora typical of riverbank forests. These species are fast growing and regenerate easily, suggesting that the community exploited the forest in a more or less sustained manner for centuries. Considering the few remaining poplar trees, the team proposes that the landscape was organized into three zones: the riverine forest, riverside scrub, and beyond, the desert. The remains of feces preserved pollen grains and phytoliths that allowed us to reconstruct both the diet of the livestock and the nature of the landscape: 83% of all that pollen came from the cattail, an aquatic plant that has historically been used as food, fiber, and even as construction material. In the case of sheep poop, the percentage rose to 99%, a figure so high that the team explains that it is probably because the animals ingested the pollen by drinking water laden with it or by breathing the air during flowering. Yes, but. The first limitation to consider is that it is not always possible to know with certainty which animal each excrement comes from and that is not a trivial matter: not knowing how to differentiate between a sheep, a goat or a camel can be a great condition on its use. On the other hand, the large presence of cattail pollen may be misleading: this plant produces large quantities and resists degradation well, so the real landscape could have had more diversity than the data suggests. The question that remains unresolved is whether the Xiaohe people grew food from the beginning or not. Current evidence suggests not, but not finding them doesn’t mean they didn’t exist.

Some millionaires wanted to build a city in the middle of a desert that did not convince anyone. They have had another idea: a shipyard

by

Residents of Solano County, northwest of the San Francisco Bay Area, realized that someone had been secretly shopping a large amount of farmland. In fact, even the army He asked who had been purchasing all the land around one of his military bases located in that county. After much investigation, it was learned that behind these purchases there was a group of Silicon Valley billionaires with a plan as utopian as it is controversial: build an entire city from scratch, in the middle of dry fields. A secret land purchase. It all started in 2018, when a company called Flannery Associates was acquiringlittle by little, agricultural plots throughout the county. The owners received figures well above the market value, but no one knew who was behind the purchase. The county itself detected that a single company was purchasing large amounts of land and asked for an explanation. It wasn’t until 2023 when it came to light that Flannery was actually the real estate arm of California Foreverand that investors had been secretly buying land in Solano since 2018, until finally announcing their true purpose: to build there a new city. By then they already had some 24,281 hectares and between 800 and 900 million dollars invested. Who puts the money. The name that shows the face is Jan Srameka former Goldman Sachs trader of Czech origin. But behind the project there are Silicon Valley investors like Steve Jobs’ widow, Laurene Powell JobsLinkedIn co-founder Reid Hoffman and venture capitalist Marc Andreessen, as well as Michael Moritz, former partner at Sequoia Capital. His initial idea was to build a walkable city in the style of New York’s West Village, designed to attract high-net-worth employees driven by housing shortage in Silicon Valley. The plan stood on paper, but I needed something to only county voters of Solano could grant: change the law Solano County’s “Orderly Growth Initiative” of 1984, known as Measure A, which protects agricultural soil. Without that permission from the citizens there was no city possible. Water, the great obstacle. That’s where the problems started. Solano It is not an area with water leftover, and the neighbors immediately saw the risk of shortage to build a new city and increase consumption. Congressman John Garamendi, one of the most critical voices of the project, assured that “From the beginning, I have maintained that the proposed project was just a pipe dream, not a real plan. Accelerating the process without a comprehensive environmental and community review would have been disastrous for the current residents of Solano County”, criticizing that the project did not take into account that it was a site without water, without sanitation and without roads. The company tried to promote a campaign to win the vote of the citizens in 2024, which became one of the most expensive in the history of the county, and even then it was not enough. The vote was withdrawn and the project was, for the moment, frozen. The turn towards the shipyard. After that blow to the continuity of the project, California Forever changed its arguments. Instead of first selling a city in the middle of nowhere, he now sells a plan of industrialization with connections to the military: a shipyard in which to build ships equipped with the latest technology in naval defense, and close to the Travis military base. The new plan pivots on two axes. On the one hand, the Solano Foundryan industrial park of about 850 hectares located just over an hour from San Francisco that aims to become the factory for robotics projects and materialize all the R&D of Silicon Valley. On the other hand, the Solano Shipyarda complex of about 3,035 hectares designed to house several shipyards dedicated to military and civil naval construction. The idea with this turn is clearly to first attract the industrial fabric and employment, and then cover the housing needs of its workers by building the city that had been projected from the beginning. Unions, Trump and what remains to be decided. To win over Solano this time, California Forever has played another card: unions. The company signed with the construction union council and the carpenters union a labor agreement for the next 40 years on the 28,328 hectares of land it owns, in which it undertakes to hire your affiliates in the construction of that city. The speech is also supported by national politics and from California Forever they defend that building shipyards on the west coast is necessary to stand up to Chinaand has sought to fit the project into the SHIPS Actthe law that Trump has promoted to reindustrialize the US naval industry. A report Commissioned by the Bay Area Council, it estimates some $215 billion in private investment and the generation of 530,000 jobs in this industrialization plan for the area. However, the shipyard remains without a permit from the county, and the chosen land is next to the Suisun Marsh protected areaone of the largest brackish water wetlands on the West Coast. Water, again, will decide if this project remains a promise or becomes something real. In Xataka | The other war between the US and China is in the shipyards Image | Unsplash (Daniel J.

an alien-looking observatory in the middle of the desert

by

Life is what happens while Saudi Arabia builds mega constructions. Or plans them, rathersince in that particular competition against the United Arab Emiratesright now there is more on the plane of ideas than on the sand of the desert. With the disaster of The Line still kickingthe country has another mega construction in mind: an observatory called AlUla Manara that seeks to become a unique tourist destination while serving as a beastly tool for astronomers. Its location is privileged, but what stands out most at first is, obviously, that design that seems more like an AI hallucination than a real building. AlUla Manara. When we talk about mega constructions in Saudi Arabia, we immediately think of Neom. The pharaonic project was not only going to house The Line, but another series of ambitious facilities, but there are other areas and projects in which the country has been injecting money for years. AlUla is a region of contrasts in which they mix World Heritage wonders with buildings that they seem from another planet. In that bag we have to put AlUla Manaraan astronomical complex that will become one of the largest optical observatories in the world. This is a project of the Royal Commission for AlUla to reinforce the role of Saudi Arabia in the international scientific community, but also seeking to position it as a new tourist pillar in the area. Peculiar design (with meaning). The images (conceptual, of course) reveal a building that is totally contrary to what we usually identify as an observatory. Instead of a huge dome that rotates and allows the telescope to be oriented, the observatory will have several more or less fixed telescopes. The main will count with four meters in diameter and will be accompanied by two others of two meters in diameter. It will not only have optical observation systems, but advanced systems such as LaserSETI that will allow monitoring the sky for flares, several observation platforms, tracking technologies and equipment for astrophotography. Integration. But, as we say, beyond the equipment, what stands out is a design signed by Heatherwick Studio, responsible for projects such as Little Island in New York or Azabudai Hills in Tokyo. The inspiration for the observatory is the spiral shapes of galaxies, as well as patterns present in fossils, although you have to use your imagination. Like the Maraya Concert Hall auditorium, full of mirrors in the middle of the desert to blend in with it, the observatory will seek not to break with the aesthetics of the region. This “flower”-shaped structure will be covered with local stone to integrate into that environment. Privileged. The AlUla Manara will be built on a plateau about 70 kilometers north of the city of AlUla and, like themselves they boastthe location is spectacular. This plateau is located in an area that is within what is known as a ‘Dark Sky Park’, a certification that makes it clear that the skies are exceptionally dark because light pollution is minimal. In fact, it is one of the best places on the planet to observe both the Milky Way and a few million other stars, which is why it will seek to exploit both the observatory’s capacity in scientific matters and monetization thanks to tourism. The visitor area will count with exhibitions, workshops and experiences designed to harness the potential of the facility and the area. But, in addition to the areas focused on tourism, there will be spaces where visitors can see scientists during their work day. Stuart Wood is the director of Heatherwick Studio and pointed out who saw an opportunity to dissolve the barriers that usually exist in this type of facilities. Let’s see what happens. All this sounds very nice and with the failure of The Line it is already difficult to believe certain things that come from Saudi Arabia, but AlUla Manara is a much more limited project that will be located in a region that already has real tourist interest and where it has been shown that this type of buildings have an outlet. Furthermore, it is a conjunction between science and tourism that is interesting and that, precisely, can make the project more viable. Now, there is still time to see that flower of the AlUla desert. The project was launched in 2023, but it was now that it was approved the final design of the complex, the scientific configuration and everything that Heatherwick Studio has in mind. It doesn’t look bad, but yes, there are still no dates on the table. In Xataka | China has no rival in megaconstructions: it even has the tallest abandoned skyscraper in the world

Spain planted millions of eucalyptus trees to have cheap wood. 90 years later, we have confirmed that they are a green desert

by

If you usually move around the Cantabrian coast, you are surely already familiar with that long and stylized tree that is so abundant in its mountains. However, the eucalyptus already covers 30% of the forest area in areas such as northwest Spain. The omnipresence of the eucalyptus is the result of a forestry policy that started in the 40’s whose main objective was to supply the paper industry: it was cheap, it grew quickly, so it had all the potential to be the ideal candidate to repopulate unproductive forests. Decades later, a scientific study of the University of Santiago de Compostela and the CSIC has put numbers to suspicions: For the fauna, these plantations are almost a desert. The environmental cost of the ubiquitous eucalyptus. This research analyzed 240 areas of native Atlantic forest and eucalyptus forest in the Parque Natural das Fragas do Eume and They found an abysmal difference in richness and abundance of birds. In short: the more eucalyptus there is, the fewer birds live in that area and it is no coincidence. Mature eucalypts cannot replace mature trees as functional habitat and their foliage offers very limited support for birds. The most affected are those that eat insects and those that breed in the holes of old trees, such as the great woodpecker or the great tit. The eucalyptus does not generate enough insects to feed on, it has no undergrowth and it is cut down before it forms the cavities that these birds need to nest. On the less bad side, they have also found a fairly simple solution that does not involve eradicating the eucalyptus: simply letting wild vegetation grow in some areas, without clearing it. Why is it important. Because the role of forest birds is important in the balance of the ecosystem: they regulate insect pests, help in seed dispersal and act as an indicator of environmental health. In fact, the EU Birds Directive 2009/147 obliges member states to conserve bird populations in good condition and this study documents that this obligation is being breached in the most eucalyptus of Galicia and the Cantabrian coast. The situation is more complicated than it seems because already in 2017 the scientific committee of the Ministry for the Ecological Transition recommended include eucalyptus in the Catalog of Invasive Exotic Species in 2017, but the proposal was rejected due to the economy behind it: in Galicia this sector generates 2.5 billion euros annually in wood and paper pulp and employs more than 19,000 people, according to the report A Cadea Forestal-Madeira de Galicia 2025 prepared by XERA. It is a complete conflict of interest. Context. The eucalyptus arrived to the Iberian Peninsula in the 19th century for ornamental and medicinal purposes, but its true boom arrive with the repopulation plans of the Franco regime and the commercial demand for cellulose. Parque Natural das Fragas do Eume, the place where the analysis was carried out, is one of the last remaining coastal Atlantic forests on the Iberian Peninsula. There, eucalyptus plantations are currently the second largest type of forest: 1,340 hectares, only behind the native forest. But the species has already colonized its surroundings. In any case, the problem with eucalyptus trees is not local: in Portugal the eucalyptus already covers more than 800,000 hectares and is the most widespread forest species in the country. according to data from the National Forest Inventory of Portugal prepared by the Instituto da Conservação da Natureza e das Florestas. It is also under scrutiny there due to its relationship with large fires. In fact, on a global scale the scientific community has been documenting for years the impact of eucalyptus on Mediterranean and temperate ecosystems outside its native Australia. In detail. Eucalyptus is a silent killer: it releases chemicals that prevent the growth of other plants under its canopy (allelopathy), which eliminates native shrubs and with them, the insects that feed the birds. Furthermore, since it is cut down every ten or fifteen years, it never ages enough to develop the holes needed for nesting by cave birds such as woodpeckers. The problem does not stay on land: dead eucalyptus leaves release oils and toxic compounds when they reach river courses, harming aquatic insects and amphibians that form the base of the river food chain. Yes, but. The damage to the diversity of the eucalyptus is a reality as undeniable as its socioeconomic importance: it is an economic vector and population fixation in these rural areas and eliminating or restricting its cultivation would have a notable impact in communities where alternatives are not abundant. Hence, the study itself does not call for its eradication, but for something simpler and more practical: leaving strips of vegetation uncut within the plantations so that the native flora can recover and the birds can return. It is a low cost solution that has already proven to be effective in other European contexts. On the other hand, there is the limitation that the study has been carried out in a single forest and is focused on birds. Not all species respond the same. In any case, science does not say that eucalyptus is evil, only that covering 30% of your forests with it has a serious biological toll.

We believed that cities were a desert for bees, but 5.5 million live under this cemetery in New York

by

Although cities have their own fauna, the reality is that one could reasonably think that for animals of all kinds the urban environment is far behind the countryside in diversity and quality of life: there is a lot of asphalt, noise, pollutants… well yes, but no, because there is a place where bees have found a true residential paradise: a cemetery in IthacaNew York. Where you see a cemetery, the bees see paradise. It turns out that a laboratory technique called Rachel Fordyce had a trick to get to your work at Cornell University without paying for parking: park on the other side and take a walk through the East Lawn Cemetery. In spring 2022 he arrived at his post with a jar full of bees that he had found along the way: that was the beginning of it all. The bees inside were Andrena regularis, known as the “common mining bee,” a wild, solitary species that nests underground. That is, it does not have a queen and it does not build hives either. Each female digs her own tunnel, lays her eggs, supplies them with food, and seals them. And under the ground of the Ithaca cemetery there are millions, more specifically 5.56 million in just over 6,000 square meterswhich come out every spring to pollinate the surrounding apple trees. Why is it important. Because it is the largest population of wild bees with a nest in the ground ever documented and very far of the secondof 1.6 million individuals of a different species in Arizona. And their work is essential: pollinators in general are responsible for the production of approximately 75% of the world’s food crops. according to the FAO. As explains Bryan Danforthprofessor of entomology at Cornell University, they must be protected: “If we don’t preserve nesting sites and someone paves them, we could instantly lose 5.5 million bees that are important pollinators.” The most striking thing of all is that this enormous population was there, in the midst of civilization and next to one of the most prestigious universities in the world. Context. Contrary to popular belief, the most common way of life for bees is solitary and with a nest on the ground: approximately 75% of the bees on the planet live like this. Those bees that produce honey and live in hives may be the most famous, but they are an absolute minority. Solitary wild bees are not as well known, but their pollination work is key in nature and in food. Thus, this enormous population lives independently but concentrated in that place because the substrate conditions are optimal. The bad news is that pollinators are in decline: according to the report of the Intergovernmental Platform on Biodiversity and Ecosystem Servicesmore than 40% of pollinating insect species are threatened. In this scenario, finding such a large population in a city shows that there are more refuges for biodiversity than we thought and we must find them before they disappear (and if possible, avoid it). In detail. We knew about the presence of Andrena regularis in that cemetery since 1935, but it was not until 2021 when the scientific community began to intuit what was underground. To estimate the population, the team installed mesh traps at 10 points in the cemetery between March 30 and May 16, 2023. The result was extraordinary: as explains the press release from the New York university, is the equivalent of 200 honey bee hives on just 0.6 hectares of land and more than triple the population of Manhattan. Yes, but. The study has important limitations, such as that the population data is from a single spring (2023) and that the figure is a statistical estimate and not a real inventory, so we do not know if the population is rising, falling, remaining stable or how climate change affects it, which is advancing the flowering of apple trees and therefore altering the life calendar of the bees. And although it is the largest aggregation of wild nesting bees documented to date, its presence in a cemetery suggests that there may be others whose existence we are unaware of.

Arab Emirates has oil and desert in abundance. Now they have discovered how to take advantage of sand: turning it into brick

by

Although transport or energy are the sectors that first come to mind when we talk about emissions, there is a third industry with a comparable share of responsibility: construction, responsible for 34% of global CO₂ emissions, according to the International Energy Agency. The problem is in the materials: manufacturing a ton of Portland cement emits between 0.6 and 0.8 tons of CO₂ both due to the energy consumed in the process and the chemical reaction that produces it. So any idea to replace classic construction materials such as concrete and brick is good to decarbonize the industry. We have already seen alternatives such as the shells on the beachbut to a company in Dubai Another idea has occurred to him: instead of importing materials, manufacture them with abundant resources in the area. More specifically, with sand and date seeds. The invention. The star product of ARDH Collective, which is the name of the Dubai company formed by Alhaan Ahmed, Alyina Ahmed and Máximo Tettamanzi, is DuneCrete: An alternative to concrete made from locally sourced desert sand, which reduces cement content by 50%. From there they manufacture the DuneBlockthe building blocks. In their product catalog they also have the Dateforma material that reuses 1,000 date seeds per square meter. Why is it important. Because after water, sand is the second resource we consume the most. The United Nations Environment Program esteem that up to 50,000 million tons of sand and gravel are consumed annually worldwide. Removing sand from rivers and coastal ecosystems causes erosion, damages water supplies, harms biodiversity and reduces storm protection, so replacing it with underused desert sand would be a turning point. DuneCrete reduces cement content by 50%, which according to its founders represents approximately half the carbon dioxide emissions compared to conventional concrete. It makes sense: Portland cement alone is responsible for 8% of global emissions and its footprint does not disappear using renewable energy, since much of it comes from a chemical reaction, not from burning fuel. Context. Paradoxically, the UAE has to import sand even though it is basically a desert. The underlying problem is that desert sand particles are rounded due to wind erosion, which makes their adhesion in conventional concrete mixtures difficult, while river sand has more angular particles that favor compaction and resistance. In detail. This project arose during a master’s degree at the Architectural Association School of Architecture in London. After obtaining a couple of grants totaling $8,000, they began research in a laboratory that they set up in the garage of one of their homes in Dubai during the pandemic. That was where they found the formula that stabilized the mixture with desert sand. Laboratory tests confirmed that the material met the resistance standards necessary for commercial development. The company start production in 2021. Yes, but. Once the problem of the geometry of desert sand has been solved, there is another obstacle to solve to scale the project: its morphology varies enormously by region and is not homogeneous.

As towns dry out and the desert advances, women in Morocco climb the mountains to capture the fog and turn it into drinking water

by

A chance experiment took place in the 1980s. Some researchers working in the Atacama Desert accidentally left a simple metal mesh exposed to wind at night. The next morning they discovered that it was covered in water droplets in one of the driest places on the planet. That seemingly trivial scene ended up inspiring an idea that decades later would change the lives of entire towns. Capture the fog before it disappears. As the desert slowly advances over southwestern Morocco and traditional wells begin to dry up, several villages in the Aït Baâmrane region have found a solution which seems closer to a science fiction image than to conventional hydraulic infrastructure: capture the fog from the mountains and convert it into drinking water. For generations, the women of these communities spent up to four hours a day walking to remote wells and returning carrying barrels weighing almost 25 kilos on their heads. That routine organized the entire life of the villages, kept many girls out of school and reflected the extent to which the lack of water conditioned any daily activity on the edge of the Sahara. Giant nets convert air into water. The change began when huge polymer networks They appeared on the slopes of Mount Boutmezguida, at more than 1,200 meters above sea level. The idea is surprisingly simple: take advantage of the moisture from the Atlantic fog that regularly passes through the Anti-Atlas mountain range. The tiny droplets become trapped in the mesh, condense and end up descending towards deposits connected to kilometers of pipelines by gravity. Without complex pumps or large industrial infrastructure, the system manages to carry water directly to homes using only wind, altitude and ambient humidity. Thanks to the advances in materials engineeringthese modern networks are much more efficient than the experiments carried out decades ago in countries like Chile, Yemen or Eritrea. And the fog reached the tap. When the system went live, neighbors gathered to see something they had never seen before: water coming directly from a faucet inside a home. That “fog water”as they began to call it, quickly transformed the daily life of the villages. Women stopped spending part-time carrying water and many girls were able to attend school regularly again. The project, promoted by the NGO Dar Si Hmadnot only modified water management, but also the social balance of communities where transporting water had been an exclusively female responsibility for centuries. The cultural challenge of drinking water that did not touch the ground. The technology worked from the beginning, but convincing everyone was much more difficult. Some inhabitants they distrusted of a water that had never passed through the earth and that, as they believed, lacked minerals and “life”. The fog represented something ambiguous, almost unreal, too far from traditional sources. Over time, the rejection disappeared as the families verified that the water was safe and constant. The transition also forced us to work unexpected social issues: Some women felt that they were losing part of their central role in the home by no longer being in charge of fetching water. That is why the project ended up incorporating literacy, technical training and community management along with hydraulic infrastructure. Finding water is impossible. The UN has recognized this May 2026 that the Moroccan system is one of the more interesting examples of climate adaptation against desertification. The project shows that some extremely dry regions can still take advantage of invisible resources which until now were hardly used. However, it also makes clear that does not exist a universal solution: capturing fog only works where mountains, ocean humidity and very specific atmospheric conditions coincide. Still, the image is powerful for a planet increasingly affected by water scarcity: as wells empty and temperatures rise, there are entire communities in Morocco that have literally begun to harvest clouds to survive.

The Strait of Hormuz has become a death trap. The Arab Emirates’ solution is a pharaonic oil “bypass” through the desert

by

The new energy order is not debated in suit and tie summits, but is rising against the clock under the scorching sun of the Arabian Peninsula. Suffocated by the Third Gulf War, the United Arab Emirates has hit the table: it refuses to leave the survival of its trade routes in the hands of chance, war or its neighbors. The strategy is clear: if the strait is a minefield, they will build a rear exit. The news that has shaken the foundations of oil logistics came to light through official channels. According to a statement from the company itself ADNOC (the Emirati state oil company), His Highness Sheikh Khaled bin Mohamed bin Zayed has chaired a key meeting in which he has ordered an urgent directive: to accelerate the construction of the new “West-East Pipeline” project. But what infrastructure are we talking about exactly? As energy analyst Javier Blas points outthe key to this movement is that the Emirates is laying out a second oil pipeline expressly designed to turn its back on the Strait of Hormuz. The date marked on the calendar is 2027. When they open the tap, this new infrastructure will double the volume of crude oil that the country takes out to the world through the port of Fujairah (in the Gulf of Oman). In practical figures, this represents a gigantic leap: they will go from the 1.5 million barrels a day that they move right now, to injecting between 3 and 3.5 million. It is not a project improvised in the last week. As analyst Bachar El-Halabi points outwork on this project began quietly in early 2024, long before the war in Iran paralyzed the region. However, the conflict has acted as the definitive “catalyst.” The war did not inspire the pipeline, but it has injected it with urgency. The logistical “antidote” As was discussed in the middle Amwaj Mediathe Iran war has starkly exhibited the tremendous vulnerability of maritime bottlenecks (chokepoints). The near-total shutdown of Hormuz has caused the worst supply disruption in history, removing 12% of the world’s oil from the market. In this context, the West-East pipeline stands as a lifeline. This Emirati infrastructure, added to the gigantic oil pipeline East-West (or Petroline) of 1,200 kilometers that Saudi Arabia has reactivated towards the Red Sea, form a true logistical “antidote.” They are escape routes that neutralize Tehran’s blackmail, allowing crude oil to go out into the world without entering the range of missiles and blockades in the Persian Gulf. They are, in the words of experts, “buying invaluable time” for the West. To understand the privilege of having this infrastructure, just look at the neighboring country: the situation in Iraq exposes the other side of the coin. Lacking alternative outlets to the sea and completely dependent on Hormuz, Iraq has been left without physical space to store its own oil. As a result, Baghdad has been forced to shut down 70% of production in its prolific southern fields and beg the Kurdistan region to let them use an old, patched-up pipeline to Turkey that barely manages to export 250,000 barrels a day. Iraq is a hostage to its own geography; The Emirates, on the other hand, are buying their freedom with steel and engineering. A free (and flooded) market by 2027 All this new logistical muscle takes on its true meaning when it intersects with another historic decision: the Emirates’ slamming of the door on OPEC+. Emirates has formally left the organizationarguing the defense of their “national interest.” After almost six decades, the country has decided that its national interests no longer fit into the cartel’s quotas. The UAE had been accumulating commercial frustration for years because OPEC forced them to limit their pumping to 3.2 million barrels per day, despite the fact that the country has invested aggressively to reach a production capacity of 5 million barrels by 2027, the same year in which its new megagas pipeline to Fujairah will be ready. But as various international media explain, this divorce is not just about money. Abu Dhabi feels betrayed. The Emirates have had to absorb much of the impact of Iranian missiles and drones alone, feeling that their Arab “brothers” and the Gulf Cooperation Council were turning their backs on them. Therefore, the consequences of this schism will be tectonic. The cartel has seen its global market share plummet to 26%. When the Strait of Hormuz reopens and the West-East pipeline operates at full capacity, the Emirates will flood the market under its own rules, leaving a lone Saudi Arabia to bear the brutal cost of trying to stabilize prices in a world of extreme volatility. The cold war for the future The Emirati order, in fact, is directly addressed to Riyadh. In the silent cold war it is waging with Saudi Arabia for regional hegemony, the Emirates refuses to be a supporting actor in the face of Prince Mohamed bin Salman’s monolithic “Vision 2030.” As explained Middle East Economythe UAE can afford to leave OPEC and endure a downward pulse in prices because its break-even Fiscal is around a comfortable $45 per barrel, compared to the much greater needs of its neighbors. Thanks to diversification, the Emirates today generates 25% of its electricity with the Barakah nuclear power plant and has immense solar parks, allowing itself to use today’s petrodollars to finance hydrogen and the technology of tomorrow. However, this apparent invulnerability has a terrifying blind spot. Military analysts warn that, in the era of hybrid warfare, a steel pipe is of little use if a $500 drone can paralyze the region. The Third Gulf War already demonstrated this fragility when a drone reached the gigantic Emirati Ruwais refinery. Added to this is the panic unleashed when pro-Iranian militias explicitly threatened vital infrastructure such as the Barakah nuclear power plant. The Emirates is building its financial and logistical freedom, yes, but it is doing so through a minefield. The new West-East pipeline is ultimately much more than a … Read more
