A photographer endured temperatures of -28º and 4,000 m altitude in the Alps to capture an almost impossible image

“There are experiences that you plan for months and yet they arrive without you being prepared.” The phrase is from Angel Fuxa photographer specializing in astrophotography and night landscape portraits, and although it may sound a bit transcendental in your mouth it has a special meaning. A few weeks ago Fux ascended to a summit of 4,200 meters above sea level and, in the middle of hellish conditions which included temperatures of -28ºC, strong gusts of wind and icy ledges where a wrong step could be fatal, obtained one of the most impressive images of the year. Even has attracted attention from NASA. Photographing the darkness. Angel Fux (Paris, 1998) is not just a talented photographer. Over time he has specialized in a fascinating branch: astrophotography and portraits of night mountain landscapes. That obsession has taken her to the Alps, Andes, Pyrenees or the Dolomites, among other regions. “My search for dark skies has intensified over the years in a way that I did not understand until recently,” recognize on his blog. Some time ago Fux was fascinated by the darkness in the Peruvian Andes and in 2025 she ascended to Gornergrat (Pennine Alps) to enjoy a similar experience with your camera at 3,000 meters above sea level. From each expedition he returned to his studio with hypnotic photographs that fueled his ambition, so a few months ago he asked himself a question: Why not go further and observe the night sky from almost 4,200 m above sea level? Dent d´Hérensa summit located just behind the Matterhorn, between Italy and Switzerland? Double arch captured in 2025 in Gornergrat. Image: Angel Fux A very precise objective. His idea was not only to ascend the Dent d’Hérens and aim his objective at the night sky. Fux wanted to capture a unique and ephemeral spectacle: the moment in which, with the help of a prepared camera, an astrophotographer can capture the double arc of the Milky Way. “Once a year, in the northern hemisphere, something simply extraordinary happens in the night sky. For a few days each March it is possible to see both arms of the Milky Way above the horizon on the same night, not at the same time, but along the same Earth’s rotation.” “The winter arc, a quieter, less dense band of stars, rises during the first half of the night. Then, as the Earth rotates, the summer arc rises from the other direction, bringing with it the galactic core, that unmistakable, dense river of light. Together, they form what is known as the double arc of the Milky Way.” It is not an unexplored phenomenon. Other photographers have captured it in awesome images and Fux herself portrayed the double arch in 2025 from the Gornergrat, at 3,100 m. Photographers with ice axes. The challenge that Fux set for himself this year raised the bar for several reasons. To begin with, the area in which I wanted to work. It was proposed to ascend 1,000 meters more than in 2025, until the Dent d’Hérensto achieve a unique result. The reason? “Photographers don’t go there, especially in winter and even less at night. The equipment necessary for astrophotography and that required for mountaineering are simply incompatible in most cases,” relates. For his expedition he needed the help of a professional mountain guide, Richard Lehner, who participated in the project with his son, Arnaud. Squaring the circle. Another complication is that, although the natural spectacle that Fux was looking for is repeated every year, it is not always photographable. For the cameras to capture it properly, they must be other extra conditions: the right phase of the moon, a correct location for the angle of the arcs, a 360-degree clear horizon and as low a level of light pollution as possible. Even if the photographer takes care of all these factors in detail and looks for the most suitable location, there is a risk that the weather will not be good. If so, the job is in danger because, as Fux remembersthe “optimal period” to take the image is very limited: it lasts just five days, so there are years in which the spectacle simply “disappears.” Months of preparation. In your blog Fux explains in detail what the preparation process was like, but comes with knowing two pieces of information. Although the photo was taken in March, he contacted his guide half a year in advance, in September. During those six months Fux dedicated himself to planning logistics, preparing the equipment and studying how to approach the work. However, it is one thing to have a plan drawn up and quite another to have it fulfilled. Throughout the process, the Frenchwoman faced several setbacks that did not prevent her from heading to Dent d’Hérens in March with Richard and Arnaud. The three knew that there was a risk that their stay at the summit would be complicated, so they had to be well equipped. Biggest fear: frostbite. “My sleeping bag is designed to withstand temperatures down to -30ºC, with a survival threshold that extends to -50 or -60ºC. My boots are three-layer mountaineering boots, with attachable crampons. My clothing consisted of several layers, both to maintain passive heat and allow active movement,” clarify. “We also had a system of ropes and harnesses prepared, since once at the top, I had to be tied at all times when leaving the tent. The ledges that surrounded the area made any movement without a rope very dangerous.” And the technical part? fux usa a special team which includes, among other pieces, a Nikon Z6 II camera adapted for astrophotography, a Nikon NIKKOR Z 20mm f/1.8 lens and a Benro Polaris star tracker. Despite this material and his experience in the mountains, Fux had to deal with some unforeseen events that threatened to ruin the project. For example, the nights spent acclimatizing to the altitude practiced with the camera to make sure, among other things, that you could handle it with gloves. “During one … Read more

We have been looking for new weapons against superbugs for years. We have designed one at 400 km altitude

Humanity has a big problem right now that can condemn it to its disappearance: antibiotic resistance. This forces science to be in a constant search for new treatments and also for raising awareness of the responsible use of drugs. And the last place where they have found a new path of research is in space. The study. A team of researchers from the University of Wisconsin-Madison has published in PLOS Biology the results of an experiment carried out aboard the International Space Station (ISS), demonstrating that the absence of gravity not only alters cellular behavior, but also accelerates evolutionary processes that would be unlikely on Earth. Something that is undoubtedly very important, since it has been seen how phage T7a virus that has the ability to infect a bacteria to kill it, developed genetic mutations in space that would not have occurred on Earth surely. Some mutations that allowed us to attack a specific bacteria that would have been unthinkable on Earth. A changing biology. On Earth, biologists are quite clear that if a virus binds to a bacteria and infects it, it can kill it. But to understand this you have to know that on our planet the interaction of these two elements in a liquid medium is facilitated by gravity. A key factor for both beings to collide within the medium. On the International Space Station these forces disappear. The movement of the particles is almost exclusively reduced to the Brownian diffusionthat is, the random movement of particles. And here it was seen that this had a great impact on the kinetics of the infection. What happened. The first thing that could be seen is that the bacteria’s ability to divide to give new ‘children’ was reduced, causing it to increase up to four hours, making it difficult for the virus and the bacteria to meet. However, after 23 days of culture on board, the infection was successful. In this way, the viral population not only reached the bacterial population, but the selective pressure of the environment forced the virus to optimize its attack mechanisms with different mutations. Genetic engineering. By analyzing the DNA of viruses that arrived from space, the research team discovered the evolution that had taken place. In this way, it was seen how it had mutated in record time in different genes that are key, such as the one used to synthesize the ‘legs’ with which it anchors itself to a bacteria. The most relevant thing is that these mutations were not random, but a direct response to the lack of frequent contacts. Having fewer opportunities to collide with a bacteria because they replicated less, the virus evolved to be more efficient at adsorption (the process of adhering to the cell surface) once it made contact. For its part, the bacteria E.coli also responded to environmental stress. The analyzes showed mutations in the genes mlaA and hldEresponsible for maintaining the integrity of the outer membrane and the synthesis of lipopolysaccharides. This suggests that the bacteria attempted to “shield” their surface both to resist microgravity and to prevent phage entry, creating a molecular arms race different from the one on Earth. Its importance. Once this has been proven, the question is clear: why do we care? The key is that the researchers used variants of the virus that evolved in space and pitted them on Earth against strains of uropathogenic E. coli that had developed resistance to phage T7 original. And the result was spectacular: the mutated viruses killed these resistant bacteria. This suggests that microgravity makes it possible to explore an “adaptive landscape” that is inaccessible under Earth’s gravity. On Earth, evolution pushes phages down already known “low resistance” paths. In space, extreme conditions force the virus to unlock alternative genetic pathways that we did not know about until now. A new model. This discovery validates a hypothesis that has been brewing for years in astrobiology and biotechnology: space is not just a place for observation, but a unique manufacturing environment. In this way, if we can use the EES, or future commercial stationsas incubators to direct the evolution of bacteriophages, we could generate a library of therapeutic viruses that are capable of defeating the superbacteria that currently threaten global health systems. That is why it is not about artificial genetic engineering, but about using directed evolution in an environment where physical rules favor the appearance of exceptional biological traits.

Airbus’s last military drone has been designed and manufactured in Spain. Its importance is not measured only in meters of altitude

Spain has just marked a milestone in the European defense industry. Airbus is over assembly of the first SIRTAPa New Generation Tactical Dron which has been designed and manufactured in the country. It is not just a technical advance: it is a declaration of intentions about the role that is sought to play in the development of strategic technologies. The Sirtap has been assembled at the facilities of Airbus Defense and Space in Getafe. The purchase was formalized by the Ministry of Defense in November 2023, with a request for nine complete systems composed of 27 aircraft and nine control stations on land. It is there where the first prototype has taken shape, and where it is now preparing to start the Test Campaign on Earth. The Spanish set by tactical drones The tests, which will evaluate both the structure and the main components of the system and the software, will be extended during the next months. The goal: to leave it ready for your first flight Before ending 2025at the CEUS DEL INTA trial center, in Huelva. According to Airbus, the new drone has been designed to fly in extreme conditions: it can operate between -40 ° C and 50 ° C, land on unpaid tracks and stay in the air for more than 20 hours in a row. To this is added an operational roof greater than 21,000 feet (6,400 meters), which would make it an ideal platform for long -distance recognition and surveillance missions. What Airbus poses with the Sirtap goes far beyond simple recognition. The drone has been thought of as A modular platform capable of adapt to different missions: You can monitor convoys from the air, act as an armed escort, detect electronic signals, participate in electronic war operations or control borders in hostile environments. It can also be deployed in emergency tasks, such as the search for vessels on the high seas or fire support. One of the most outstanding points of SIRTAP is that it has been designed without components subject to Itar restrictionswhich, according to Airbus, facilitates its export to international markets. This feature, together with its modular architecture, opens the door to future versions adapted to different environments, such as a naval variant or with complete weapons integration. A no less detail is that the system is also designed to interoperate with existing command and control networks. The Sirtap breaks into a segment with Several established actors. Uav like him TACTICAL HERONwith its ability to carry several useful loads simultaneously and operate from semi -sighed clues, or the Bayraktar TB2known for its missions in real combat and more than one million hours of operational flight. We also find al Falco Xplorerwith its autonomy of more than 24 hours and flight roof above 30,000 feet. Given that panorama, Airbus drone proposes a promising combination: Itar restrictions free, modular architecture, interoperability with European systems and operability in extreme conditions. Its focus is not to overcome figures, but to offer an adaptable platform, easily exportable and margin to evolve towards naval or armed versions. He has not yet taken off, but his road map places him as an actor to take into account.
