the Quarterhorse is emerging as one of its great bets

by

For decades, talking about extremely fast airplanes meant talking about the same name: the SR-71 Blackbird. This American reconnaissance plane, capable of flying at more than Mach 3, established in 1976 the absolute speed record for a manned aircraft with air-breathing engines. Since then, that bar has barely moved. However, in recent years, projects have begun to appear that seek to reactivate this race for speed, and one of the most visible is the one promoted by the American company Hermeus. The program does not seek to build a single revolutionary aircraft from the beginning. Its approach is different: develop a series of prototypes that solve, step by step, the challenges of very high-speed flight. In this context appears the quarterhorse Mk 2.1, an unmanned aircraft that has already begun flight testing and is part of a broader roadmap aimed at bringing the United States closer to new supersonic and, later, hypersonic flight capabilities. The prototype with which Hermeus wants to accelerate high-speed flight To put this flight in context you have to look at the Quarterhorse program as a whole. Hermeus presents this project as a prototype chain designed to address different aspects of high-speed flight. Each device is built with a specific technical objective and the results obtained are used to adjust the next step of the program. The company defends that this rapid and iterative development model, based on multiple prototypes, allows progress to be made with greater agility than the traditional cycles of experimental aviation. The flight carried out from Spaceport America, in New Mexico, is precisely part of that process. The test was carried out in the White Sands Missile Range airspace and the device was controlled from a flight station located on the ground. According to official information, the mission focused on checking the operation of different systems and starting a test campaign that will gradually expand the flight profile of the prototype. Beyond that context, Quarterhorse Mk 2.1 introduces important changes to the program’s architecture. The plane has dimensions comparable to those of an F-16 fighter and uses a delta wing configuration optimized for high-speed flight. The device also incorporates a variable air intake and is powered by a Pratt & Whitney F100 engine, a turbofan widely used in military aircraft such as the F-16 itself. The prototype is conceived as a remotely piloted unmanned aircraft. During the tests, the device is controlled from a flight station on the ground, from which operators monitor the systems and behavior of the vehicle in real time. According to Hermeus, this type of architecture makes it possible to carry out tests progressively and collect detailed data on aerodynamics, control and operation of the systems before expanding the flight profile of the device. The first flight of the device It is part of a larger test campaign aimed at checking how the aircraft performs in real conditions. In addition, the mission was designed to validate different systems of the device, evaluate its stability in flight and confirm that operating procedures are working as planned. During the test, the plane was controlled from a flight station on the ground while operating in the airspace of White Sands Missile Range, in New Mexico. This type of campaign is developed gradually. On the first sorties, engineering teams usually focus on verifying the general operation of the device and collecting data on its aerodynamic behavior and control in flight. With this information, the aircraft’s parameters are adjusted and new tests are planned that allow the flight envelope to be progressively expanded before attempting to reach higher speeds. Within the program’s roadmap, Mk 2.1 is not the last planned step. Hermeus places this device within a series of aircraft that are part of the Mk 2 phase, whose objective is move towards supersonic flight. Following initial testing, the company hopes to progressively expand the prototype’s flight conditions and use the data obtained to prepare the next vehicle in the program, the Quarterhorse Mk 2.2. Therefore, this future model will be in charge of trying to overcome the sound barrier. The strategy consists of distributing the technical challenges between different prototypes, which allows risks to be reduced as new capabilities are incorporated at each stage of the program. Reaching these levels means facing very complex aerodynamic forces and extremely high temperatures in the air. airframe. For this reason, the development of this type of aircraft is usually carried out gradually, expanding the flight profile step by step to prevent an experimental prototype from becoming a costly failure during testing. The development of aircraft capable of flying at very high speeds also responds to broader strategic interests. Some of the technologies being tested in the Quarterhorse program could be used in the future for missions such as rapid cargo transportation or reconnaissance tasks. It is important to note that the program is still in an early phase of development. The recent flight marks the beginning of a test campaign that will have to be progressively expanded before the project can demonstrate more ambitious capabilities. For now, The prototype has begun its tests and that the program continues to advance within the established roadmap. The next steps will allow us to verify to what extent this plan can materialize.

We thought that human beings began to walk in Africa. This 7.2 million-year-old fossil says otherwise

by

The scientific consensus has been telling us for decades that the cradle of humanity and the origin of our ancestors who began to walk on two legs was in Africa. However, a new paleontological discovery in the Balkans just launched an order to this official story. More specifically, a fossilized femur that suggests our earliest ancestors may have started walking on two legs in Europe. A bone. The centerpiece of this discovery is a femur cataloged as FM3549AZM6 and found at the Azmaka site, in Bulgaria. From this, the research team began to analyze the bone down to the millimeter, highlighting above all the anatomy it had. Researchers here have identified key biomechanical traits that point to partial bipedal locomotion, meaning that our ancestor could walk on two legs. Specifically, they have seen that the neck of the femur is unusually long and it has specific muscle insertion points that strictly arboreal primates do not have. These characteristics suggest that Graecopithecus He spent considerable time walking upright on the ground. A new hypothesis. This finding does not come out of nowhere, since in 2017 this same team of researchers already raised eyebrows in the scientific community by suggesting that the evolutionary divergence between humans and chimpanzees could have occurred in the eastern Mediterranean, and not in Africa. That hypothesis was based on analysis of a jaw found in Greece and a tooth from Bulgaria attributed to Graecopithecus freybergi. Now it comes to light again. At that time, definitive proof of locomotion was missing, but Azmaka’s femur fills that gap that we needed to begin to reach clear conclusions. Why did they stand up? Evolution rarely occurs without a strong environmental push, and the Europe of 7 million years ago looked nothing like it does today. Here investigations at Bulgarian sites, such as the Struma Valley, show that the landscape was dominated by a savanna environment very similar to the African one, caused by a global confrontation and severe droughts in the Mediterranean. This loss of dense forests would have forced the region’s primates to come down from the trees and adapt their movement to travel long distances in open fields in search of food. In this way, it was geography and not the continent that forced bipedalism. The debate. The new Bulgarian femur revives one of the hottest debates in paleontology, since until now, the title of the oldest bipedal hominin was held by Sahelanthropus tchadensisabout 7 million years old and found in Africa. But now, if this team’s dating and analysis are accurate, Graecopithecus would not only equal, but slightly surpass in seniority Sahelanthropusmoving the “kilometer zero” of bipedalism to the Balkans. But at the moment it is too early for the textbooks to change definitively, since, as with previous discoveries, the scientific community will demand more independent analyzes and will seek to debate every notch of the femur. What is undeniable is that the African monopoly on the origin of our lineage now has a serious European competitor. In Xataka | Humans are evolving live on the Tibetan plateau.

a clash of moons 100 million ago wants to solve it

by

Few planets in the Solar system are as recognizable as Saturn and its characteristic rings. They may not be as visible to the naked eye, but around them there are also an impressive 274 moons. Well, according to a recent study from the SETI Instituterings and moons could be linked by the same event: a colossal collision 100 million years ago that left Saturn’s environment as we know it. Context. The first time we approached Saturn was in 1979 with NASA’s Pioneer 11. A few years later, Voyagers 1 and 2 flew over it. It was the probe cassini on a 13-year mission that shed some light on this planet, its rings and its moons. Cassini discovered three anomalies that did not fit the models proposed by astronomy: The rings are about 100 million years old, much younger than the billions they expected (friendly reminder: The solar system is 4.6 billion years old) Several moons had strange, asymmetrical and unbalanced orbits. Saturn’s internal mass is more concentrated in the center than predicted. The previous hypothesis. In 2022 a team of astronomy professionals established a hypothesis to explain these anomalies: the explanation could be that Saturn had lost a moon about 100 million years ago, precisely the date on which the youngest rings were formed. The discovery. Based on the previous hypothesis and after several simulations, they arrived at the explanation that where Titan orbits today there were two moons: a Proto-Titan and a smaller Proto-Hypérion. At some point they collided and the Proto-Titan absorbed the other. What was not integrated was regrouped forming the current deformed and asymmetrical Hipérion. This process explains why Titan does not have craters on its surface and its eccentric orbit, inherited from the perturbations prior to the impact. Because of this irregular orbit, Titan destabilizes Saturn’s inner moons, throwing them outward and thus causing cascading collisions between them. In short: Saturn’s rings would be the scar of this process, not the original characteristic of the planet, but the result of a chain reaction of destruction caused by the collision between two primitive moons. Diagram of Saturn’s rings from NASA Why it is important. Because Saturn’s rings are no longer seen as an aesthetic curiosity and become what they truly are: fossils of cosmic events. Furthermore, it requires reviewing the models proposed by the scientific community until now to expand knowledge about planetary formation in general. Without going any further, it provides more information about similar systems, such as that of the Earth and the Moon, whose origin is also attributed to a primordial collision. On the other hand, Titan has a strategic importance in humanity’s space plans: it is one of the most interesting candidates in the search for life thanks to characteristics such as its dense atmosphere or its methane oceans. Knowing its origin is not only a historical question: it is understanding what conditions made it possible and whether something similar could be repeated in other worlds. How they did it. Starting with the 2022 hypothesis, they applied computer simulations to check whether an additional moon could get close enough to Saturn to form rings. The goal was to recreate the solar system over thousands of iterations until the results matched the Saturn environment we know. The SETI Institute team, led by Matija Ćuk, got here after introducing an additional unstable moon that always ended the same way: with Hyperion disappearing again and again. It was the sign that a premise was incorrect, so they proposed something new: and what were there were two extra moons? Yes, but. Although this study offers a plausible explanation of the current Saturn environment, it is still based on simulations. There is no direct physical data from Titan. In fact, the team itself recognizes that they need more data. That’s where the mission comes in. NASA Dragonflywhich could provide more essential data to understand why the rings formed. This drone from the North American space agency will land on Titan in 2034 to analyze the chemical composition of its surface, which could reveal traces of the primordial impact and confirm (or not) that Titan is really the result of a merger.

a widespread error reveals that the coasts are much more exposed

by

One of the great ‘fears’ we have regarding global warming is the rise in sea level and the risk of floods in coastal locations in much of the world due to the melting of the poles. But now we have bad news: the vast majority of scientific studies on the risk of coastal flooding have started from the wrong premise. And it is not a miscalculation in the thaw or in the CO₂ emissionsbut we have been measuring wrongly where the ‘zero’ is. They have realized. This is what has been revealed by a new study published this month March in Nature that has shaken the foundations of coastal climate projections. Here the research has pointed out that the sea level on the coasts is, on average, about 30 centimeters higher than what the risk models assumed. And in some areas of the planet, the difference exceeds one meter. How is it possible? To understand where the problem is, you have to look at how a flood risk map is created. When researchers calculate which areas will be underwater if sea levels rise, they need a starting point like a baseline, and the problem is that this starting point was very wrong. The problem. To reach this conclusion, the researchers reviewed 385 peer studies published between 2009 and 2025 and discovered a pattern: more than 90% of these investigations used “theoretical geoids” to mark this baseline. The problem is that a geoid is an idealized gravitational model of the Earth that assumes an ocean at perfect rest. However, the real ocean is far from being completely at rest, since there are different factors, such as prevailing winds, ocean currents, water temperature and salinity, that cause water to accumulate more on some coasts than on others. That is why when the researchers compared these theoretical models with the real measurements obtained through satellite altimetry and tide gauges, the discrepancy was evident. They change the world. At a global level, if this correction is adjusted to real factors, the underestimation of coastal sea level is between 24 and 30 centimeters. And although it may seem like a manageable figure, in coastal topography 30 centimeters makes the difference between a dry promenade and a flooded city. The most worrying thing is the geographical inequality of this error, since, while in some areas of the global north the deviation is smaller, in the South the effective sea level becomes one meter or more higher than what had been projected. But there are even exceptional areas where extreme figures of up to 5.5 or 7.6 meters are reached. Greater risk. By applying these new models of the seas, the Wageningen researchers discovered that, given a projected 1 meter rise in sea level, the coastal area at risk of flooding is 37% greater than previously thought, which puts an additional 132 million people in the danger zone. The rhythm does not change. Although this may seem like we are experiencing an increase in the speed of sea level rise, the truth is that everything remains at the same point, and with a speed that remains the same as that at which it had been previously measured. What changes in this case is the starting point, since by starting from a base that was too low we were experiencing a false sense of security. This means that we are now closer to the critical flood thresholds than we thought, so the time margin we thought we had to build dams, relocate populations or adapt infrastructure in megacities in Asia or on Pacific islands has just been drastically reduced. The next step. To solve this historical “blind spot”, the research team has not limited itself to pointing out the error that has been made, but has processed the corrected data using supercomputers and published it openly. The goal here is for governments and climatologists to be able to recalculate their coastal risk maps using the actual sea surface and not a theoretical globe.

There is a luxury development in Madrid that has been “hidden” for years and is stealing the spotlight from La Finca and La Moraleja

by

If we think about luxury developments in Madrid, names like La Finca or La Moraleja probably come to mind. However, there is a new player on the Madrid luxury real estate board, one that has gone unnoticed for decades and has recently become fashionable among the richest. Low profile. Álamos de Bularas is an urbanization that has been standing since the 1980s, but has gone unnoticed in the shadow of more high-profile names such as its neighbor La Finca. Its strong point is precisely that: combining luxury and exclusivity with a lower profile and less media noise than other areas. But just because it is not the most famous urbanization does not mean that it does not offer high-level luxury; a search on housing portals most popular returns us a few properties that border and even exceed 4 million euros. Tranquility is what is most sought after. Like other luxury developments such as La Finca, Somosaguas or Monte Alina, our protagonist is located in Pozuelo de Alarcón (which by the way is the richest municipality in all of Spain) specifically in the northwest area. Álamos de Bulara is a fairly small urbanization, located next to Monte del Pilar, a forested area of ​​about 800 hectares. Access is closed and has private security. The location factor. In statements to the AD Magazinethe head of the Ketier real estate agency highlights that location is a key factor for more and more buyers to look at Álamos de Bularas. The urbanization is very well connected, with access to both the M40 and the A6, allowing its residents to be in the center of Madrid in less than half an hour and in the center of Pozuelo in just 10 minutes. In addition, it is very close to some prestigious private schools and sports clubs. The new refuge for VIPs. The housing crisis is also impacting how and where the wealthiest shop. We were recently talking about luxury apartments in Madrid were so expensivewhich urbanizations like La Moraleja or La Finca were becoming more “affordable” options“for the great fortunes. According to a Colliers report A year ago, the square meter in neighborhoods such as Salamanca or Chamberí reached peaks that exceeded 27,000 euros per square meter. This has caused many buyers to seek residence in peripheral areas, where demand has increased.

We have not understood for decades why chronic pain punishes women more. Finally we have the answer

by

Historically, medicine has grappled with an undeniable gender gap in which women Women suffer chronic pain more frequently than men, and on top of that their pain flares for much longer. This is something that many doctors have considered ‘normal’ and has been dismissed with psychological biases. But now science has seen that an explanation should not be sought in the mind, but in the immune system. Against pain. This is the objective that medicine has right now, since it is undoubtedly a situation that for many people can be unbearable. That is why the magazine Science Immunology publish now a new study that offers a paradigm shift in our understanding of the biology of pain. The result of this is that he has managed to find the key to some types of white blood cells called monocytes and in its direct relationship with testosterone. What’s happening? When an injury is suffered, such as a blow, the body tries to defend itself with an inflammatory response. One of its components is pain, which is a necessary alarm signal to warn that something is wrong, but once the tissue begins to heal, it is logical that this alarm goes off. But this is where the body’s defense cells come in, monocytes, which act as ‘firefighters’ by releasing proteins called interleukin-10. Here the research team has been able to see that this interleukin-10, abbreviated as IL-10, acts directly on sensory neurons to “turn off” hypersensitivity and therefore pain. The problem, and here lies the importance between sexes, is that men resolve this inflammatory pain much faster because they produce a greater amount of this protein. The reason. Testosterone. This male sex hormone stimulates monocytes to produce higher levels of IL-10 after injury, and therefore pain can be better reduced. But in women this level of testosterone is much lower, and therefore the production of this natural ‘painkiller’ is lower, which causes the sensory neurons to take much longer to stop giving the signal that generates pain. Your demonstration. Beyond doing so in animal models, the research team has been able to validate the experiments with human data from the AURORA studiowhich is a project that evaluates patients who have suffered traffic accidents and severe trauma. Here the clinical data confirmed the laboratory’s suspicions, since they saw that the elimination or reduction of IL-10 activity in monocytes significantly delays the resolution of pain in both sexes, validating that this hormone-mediated immunological difference is exactly the same in humans. In the future. This discovery is not just another biological curiosity to close a historical debate, but it has important therapeutic implications. And right now the severe pain crisis has to be treated with opiates on many occasions, which have a long list of side effects. But upon discovering this cellular mechanism, the researchers tried administering Resolvin D1a compound that promotes the resolution of inflammation. Here it was clearly seen how pain was reduced equally in both sexes. This is why we are at the gateway to a new generation of non-opioid therapies that specifically modulate the immune system. But what is most important about this study is that it highlights the need to leave behind the “one size fits all” model in medicine to move towards more personalized medicine.

It is capable of compressing space and time

by

15 meters deep, in a basement of Zhejiang University, China has installed a machine the size of a building capable of doing something hitherto impossible for a laboratory: reproducing in hours what nature takes centuries to build. Or destroy. Its name is CHIEF1900 and it can rotate at extreme speeds or generate a gravitational force a thousand times greater than that of the Earth, which for example serves to simulate an earthquake and its effects. Context. For a geology professional, analyzing a portion of land means deciphering the history of the planet in layers: each stratum is a record of millions of years. The problem is that nature writes it slowly. Reproducing this phenomenon in a laboratory has been one of the great challenges of experimental physics for decades. Hypergravity centrifuges are the tool that comes closest to that goal. These machines are capable of rotating at extreme speeds, generating forces hundreds or thousands of times greater than Earth’s gravity. When rotating, the arms generate outward pressure on everything inside the machine. The faster it is, the greater the force. The result is a controlled hypergravity field that compresses time and distance. What China has achieved. Zhejiang University (Hangzhou) has completed the construction of the most powerful hypergravity centrifuge in the world: it will have a total capacity of 1,900g·ton, that is, it can apply 1,900G to a one-tonne sample. The CHIEF1900 will surpass the record that China had established a few months before (September 2025), with the CHIEF1300. This power makes it possible to replicate land deformations on a kilometer scale, simulate the transport of pollutants over millennia, evaluate the resistance of a dam to an earthquake or generate thousands of new material samples. As a reference, with the CHIEF1300 they have already been able to reproduce the pressure of the seabed at a depth of 2,000 meters to evaluate the extraction of methane hydrates, or simulate how a 20-meter tsunami affects the seabed. Why is it important. To natural disasters such as earthquakes or tsunamis we have to add other consequences of human activity such as the breaking of dams, contamination of aquifers or deformation of the soil under high-speed infrastructure or the melting of glaciers. Predicting how these phenomena will behave requires information that is not available since obtaining them in real conditions is either impossible or would take decades. Dan Wilson, deputy director of the Center for Geotechnical Modeling at the University of California, explains for Popular Mechanics that this will be one of the four largest dynamic centrifuges in the world, that is, it can simulate active earthquakes using hypergravity. Chen Yunmin, chief scientist of the project, sums it up accurately: It aims to create experimental environments spanning from milliseconds to tens of thousands of years, and from the atomic to the kilometer scale. How they have done it. To build a machine with such performance, Zhejiang University brought together a multidisciplinary team that brings together personnel specialized in civil engineering, thermodynamics or automation. Among the technical challenges they faced was heat: at high rotation speeds, the centrifuge reaches such temperatures that the stability of the system is compromised. The solution was a cooling system that combines vacuum, forced ventilation and glacial coolant. The fact that the installation is buried has an explanation: it minimizes external vibrations, which could contaminate the experiments to be carried out. Pending subjects. Although the installation dates back to the end of 2025 and Popular Mechanics mentions which is already operational, no scientific results from CHIEF1900 are yet available. At an operational level, these scale models reproduce the loads well but not always all the size effects: certain material behaviors do not scale linearly under hypergravity, which requires caution in the interpretation of results. To minimize this risk, it is common for the data obtained to be compared with that of other similar facilities around the world.

why the United States needs the old continent more than it admits

by

That the United States is the absolute reference of the West is a reality that we have been seeing all our lives: American Way of Life from the 1950s to the hackneyed phrase “without us, you would all be speaking German” that Trump took it upon himself to remember in Davos and that we have seen countless times in war films. Spain has its own version of that story with Welcome, Mister Marshall. But Trump returned to the White House willing to fulfill his promise to “Make American Great Again” at any price: immigration management with ICE as the executing arm about their citizenship, threats to Greenland or tariffs as a tool of permanent pressure. His ways are more reminiscent of a school bully than of a leader running one of the most powerful countries on the planet. And Europe? Well, between caution, diplomacy and even turning the other cheek. The million-dollar question is whether Europe has as little room for maneuver as it appears. The answer, according to a recent analysis from the German institute Dezernat Zukunft, no. United States > Europe. In case it was necessary to remember the power of the United States in general, it has the largest GDP in the world according to the IMFit is also the country with more military spendingthe dollar It is the world reserve currency par excellence since 1945. Furthermore, leads in digital infrastructure and semiconductors (in design and sales), almost half the world share. In fact, as Dezernat Zukunft points outnot even the 10 largest European countries combined compete with those key indicators of material power. But power is not negotiating ability. The United States is the strongest in the yard, but Europe has the leverage. And here the game board changes. A close example: the gas key. Russia’s GDP It is less than the ninth part of the EUbut Russia has something that Europe needs: the gas required to heat in winter. Changing suppliers overnight was unfeasible. Europe is a succulent client. The magnificent seven (Apple, Amazon, Microsoft, Alphabet, Nvidia, Tesla, Meta) have an important part of their market in Europe. According to estimates by Dezernat Zukunftthese big tech companies generate more than $500 billion annually in Europe alone. If the old continent closes the market or fines them, their stock market shares would suffer a severe blow. And this point is not only important for companies. The magnificent seven They represent a third of the entire S&P 500the index in which the pension plans of millions of Americans are invested. If these big tech companies lose Europe, North American seniors earn less when they retire and that can be dramatic on a social and political level. Europe controls nuclear fuel. On Donald Trump’s roadmap Nuclear power plants are being built everywhere, but the United States does not have enough enriched uranium to supply itself in the short or medium term. Europe, through companies such as Urenco and Orano, is the main supplier of enriched uranium to the US, according to data from the Energy Information Agency. If the EU turns off the tap by prioritizing its own supply, the United States would have a problem meeting its nuclear needs, a key element for powering AI data centers. Because in the artificial intelligence race, The US desperately needs energy. Europe manufactures the turbines. To achieve enough electricity to meet the demand of data centers for AI, a specific type of gas turbines (40 – 60 MW) is also needed and here a European company is the queen: Siemens Energy. Siemens Energy’s SGT-800 has delivery times of one to three years, in a market where general deadlines have skyrocketed to seven years due to the demand for data centers, according to Utility Dive. Europe does not even need to turn its back on the United States, prioritizing its own orders would be enough for US artificial intelligence projects to suffer a few valuable years of delay. And time is money: the cost for large US technology operators could exceed 50 billion euros, according to Dezernat Zukunft estimates. American debt is fragile. The US dollar accounts for 58% of world reserves, but its weight as a reserve currency has been declining for two decades. USA accumulate a deficit of 1.8 trillion dollars annually that is financed by issuing debt and needs buyers. The problem is that central banks have stopped buying that debt: now it is speculative investment funds based in London that support the market. For the German institute, Europe has regulatory tools to discourage the purchase of American debt and favor European debt. If American bond rates rise, mortgages, credit and public spending in the US become more expensive. And we have seen it recently: when 30-year bonds exceeded 5%, Trump backed down in their tariffs. Europe is the best customer for gas. USA is the main supplier of LNG to the EU. However, if war conflicts allow it, starting in 2027 The International Energy Agency plans a gas surplus that will change the balance: sellers will need buyers and not the other way around. Dezernat Zukunft explains that due to geographical proximity, Europe is the best customer for the US, so if the United States tried to use gas as a weapon, it would be making a fatal mistake: it would sink the profits of its gas industry and Europe could buy gas from other countries. In fact, the EU is already working on it. Who needs who more. Although from an objective and abstract point of view parameters such as the largest army or the most powerful economy make Europe look weaker compared to the United States, Dezernat Zukunft highlights one power: that of necessity. And on some issues, the US needs Europe as much or more than Europe needs the US. It is not that Europe does not have cards to play, it is that it is difficult for it to agree to play them.

2026 seems to be the year

The highway that passes through the Guadalhorce Valley and the Serranía de Ronda has been making little progress for more than a decade. And it is a shame, because it is an infrastructure that aims to alleviate all the traffic on the Málaga-Campillos-Ronda axis. The good thing is that there is beginning to be movement in the project. In fact, there are already contracts awarded and works that, if nothing happens, should begin this year. A half highway. The A-357, known as the Guadalhorce highway, connects Malaga capital with the Guadalhorce Valley and the interior of the province. It has 69 kilometers in total, but it is only a highway until Casapalma. From there, the conventional road has to support the more than 25,000 vehicles per day, although in the sections closest to Malaga the peaks reach 80,000. It is the only entrance to the capital for municipalities such as Álora, Pizarra or Cártama, and also the most direct access to Ronda for thousands of tourists and residents. Awarded in 2010, but never built. The first pending section, between the Casapalma and Cerralba interchanges (just 4.2 kilometers), was awarded for the first time in January 2010. The works, however, never began. The contract was paralyzed since then, and from the Junta de Andalucía they counted that the administration had to end up resolving it a decade later with an additional financial cost of half a million euros. The project had also become technically obsolete: since when it was restarted they had to invest money and effort in repeating the environmental procedure and updating all the documentation from practically scratch. The offers arrive. In February 2024, the Ministry of Development reactivated the project and in the summer of that same year the Government Council authorized the expense. In July 2025, The works were tendered for 56.9 million euros with an execution period of 46 months. At that time, 22 proposals were presented, most of them in the form of a UTE (temporary union of companies), with some of the largest construction groups in the country such as Acciona, Ferrovial, Dragados, Sacyr or FCC, among others. The UTE of Copisa Constructora Pirenaica and Arpo was the one who took the lead. According to Diario Surthey offered to do the work for 41.6 million, almost 15 million less than the bidding budget. What exactly is going to be built. The new section runs largely parallel to the current road, which will be maintained as a service road for local access. The new infrastructure will have a dual carriageway with two 3.5 meter lanes in each direction, shoulders and a ten meter median. It will also have a 250-meter viaduct to cross the Rio Grande. The section ends by connecting with the current highway in Pizarra through a roundabout, leaving the junction ready for the next phase. And now what. The works should start in the coming months. But this section is just the beginning. The Board has two other projects in the drafting phase that total eight more kilometers: the Cerralba-Zalea section and the duplication of the accesses to Ronda on the A-367, both awarded for design in January 2025, according to account South Journal. Beyond that, the more than 70 remaining kilometers to Ronda remain without a date or definitive route, and several groups have been asking for a clearer commitment for years. We’ll see how everything turns out. In Xataka | At 150 km it is the longest urban axis in the world and it is, to no one’s surprise, in China: connecting cities is the least important thing

Tired of being told that philosophy was just opinions, one guy set about collecting all the “philosophical facts” he could find. He got 200

Philosophy has a reputation for discussing everything and the truth is that it is a reputation that has been hard-earned. However, it is not a matter of saying the first thing that comes to mind. It’s not even a matter of opinions, no matter how informed they may be. At least, that is the opinion of philosopher Bryan Frances. In fact, Frances is convinced that, in reality, philosophers only discuss details and minutiae: in substance, they agree on almost everything. But of course, it is not enough to say it: it must be defended. So he began to do something strange for a philosopher: instead of arguing it, he began to compile this enormous core of shared truths. That is, to make a list. But let’s start at the beginning. Frances’s thesis is that, as I say, there is great agreement among philosophers about the truth of many substantive claims. What’s more, he is convinced that, in philosophy, there is progress equivalent to that of any other science. That is, “based on facts.” The thing is that discipline — for better or worse — tends to revolve around the controversial. The curious thing is that he realized that not even the philosophers themselves were aware of this. And what a list… So, neither short nor lazy, he published ‘Philosophy as Fact-Based Discipline: 200 Philosophical Facts, published in Philosophical Studies‘: the list. A list of elementary truths pedagogically comparable to introductory science material. “It’s not the deepest,” but it’s (definitely) something cumulative and useful to understand. But, beyond that, it is also a way of reclaiming the discipline in a climate that repeatedly questions the role of the humanities in the body of knowledge. And what truths are those? Once we have made it clear that it is not about talking about deep truths (Does free will exist? Why being and not nothingness? etc…), the question becomes evident: what are they then? They are simpler things like, for example, what beliefs are (which come in many formats, they can be about almost anything or they can exist even if we are not aware of them), what evidence is (which are not just tests), what biases, emotions or faith are. It’s very interesting review the 200 facts because there are very interesting things about things that one had not asked: does believing in something make it true? Does the evidence have direction? Is suspending the trial a rational thing to do? Thought in action. But beyond the facts themselves, Frances’ idea is intelligent because it points to something singular: there is cognitive progress, an ultimate structure of reality to describe, a philosophical ‘holy grail’ to find. It’s not much, I admit. But the idea that the universe is not the horrible chaos it seems is (in its own way) comforting.
