The terror of wars was always stepping on a mine. In Ukraine they carry scissors, because the panic is thinner: a spider web

In May we count that an unexpected weapon had begun to be added among the Ukrainian troops: scissors. Given the brutality of the conflict, a technology had sneaked in to evade electronic warfare and enter the enemy camp on both sides as he had not done before: destroying the lines, making attacks invisible and evading any attempt at interference. Now, the tangle of cables has intensified. A deadly web. In 2025, the Ukrainian front is no longer understood without a sky and ground crossed by thousands of drones and by kilometers of optical cable that transform the land into a physical and tactical tangle. What started as a technological revolution to compensate for human shortcomings has evolved into an industrialized war in which each innovation immediately generates a counter-innovation, and where Ukraine, which for years led the initiative, now faces a scenario in which Russia obtains a sustained advantage. Fiber optic drones (invulnerable to electronic shielding) have colonized trenches, roads and wooded areas, leaving visible and invisible networks that slow down every movement and that, in the middle of the night, they get confused with real traps. Narratives from units like the Ukrainian Rangers show a landscape in which advancing is as dangerous as retreating: cables hanging from trees, entrenched in mud, or accidentally attached to weapons and vehicles after each mission. There is no “safe zone.” The great transformation is not in territorial advances, but in the Russian ability to hit supply lines tens of km from the front. What yesterday was a rearguard today is a vulnerable gray zoneand what once required manned aviation is now accomplished by swarms of small, remotely guided vehicles. The explosions that convoys have reached on theoretically protected roads confirm that Moscow has given absolute priority to the war of attrition: attacking where it hurts most, preventing rotations, exhausting Ukrainian drone pilots and forcing brigades to walk dozens of kilometers on foot to avoid detection. This logistical pressure not only undermines military resistance, but also alters the political balance: a country that loses strategic depth also loses negotiating capacity. The Rubikon unit. It we have counted before. The appearance of Rubikon, the elite unit that reorganized Russian doctrine after the Ukrainian incursion into Kursk, marks a before and after. Recruiting the best pilots, integrating optical drones, FPV and “mother” platforms like the Molniya, they exported a lethal model to the Donbas: attack supply before infantry, eliminate enemy pilots before riflemen, destroy capabilities before positions. Its success lies less in technology than on the scale: Russia produces more, deploys more and lets China nurture its fiber optic industry without limits. In Pokrovsk (the crudest laboratory of this mutation) Ukrainian soldiers calculate that Russian drones surpass them in a ratio of 10 to 1. The city, turned into a puzzle of ruins where the front line changes every few hours, exemplifies how tactical air dominance has become the decisive factor in controlling the terrain. The Ukrainian crisis. Ukraine continues to cause severe damage in the final strip before the front, where traditional FPVs remain lethal. But the rest of the board has leaned against her: a shortage of optical cables, pilots forced to launch from ever greater distances, disrupted logistics chains and a military industry struggling to produce what Russia receives on an industrial scale. Some controls they insist in which the strategic error is to prioritize the destruction of Russian infantry instead of replicating the Rubikon model: hunt down the operators, saturate the logistics nodes and act in depth. However, any solution requires resources that Ukraine does not have and that its allies provide too slowly. Chinese fiber optics, the officers point outis tipping the balance with more weight than many Western diplomatic decisions. Between swarms and cables. The conclusion is disturbing: war no longer depends so much on territorial advances as on who controls the drone ecosystem, who has more operational pilotswho can saturate the most kilometers of enemy rear and who turns rival logistics into a prohibited zone. The front, turned into a spider web physically by wires and digitally webed by unmanned swarms, is being redefined at a speed that Ukraine struggles to match. If kyiv does not regain the technological initiative and achieve a steady supply of optical capabilities and long-range platforms, 2026 could be the first year in which Russia’s structural advantage in drones not only complicates Ukrainian offensives, but seriously limits its ability to sustain current defenses.

a 100 square meter spider web where two enemy species live in peace

He fear of spiders is one of the most common phobias. So much so that there are video games that allow you to change the design of spiders for that of other animals and there is even research into how. recreate them in less scary ways. With this I want to tell you that, if they give you the creepswhat they have discovered in a cave between Albania and Greece will be the new scene of your nightmares: the biggest spider web in the world, a megacity that has more than 111,000 spiders. And the most curious thing has nothing to do with the size of the structure. In short. A few days ago, in the magazine Subterranean Biologya team of researchers described their great discovery: in the Sulfur Cave between Albania and Greece, they had found a mega city of spiders. Actually, the initial discovery was made by speleologists from the Czech Speleological Society in 2022, but scientists from Transylvania University were the ones who visited and documented the cave in recent years. What draws the most attention is a nightmare scenario: a ‘silk’ structure that covers about 106 square meters and in which a whopping 111,000 spiders live. It is located about 50 meters from the cave entrance, in a very narrow, permanently dark area, and researchers believe there are thousands of individual funnel-shaped spider webs that have come together to create the structure. The colony. For that reason alone, the find is worth mentioning, but the most interesting thing is not the size, but rather the people responsible. If we were talking about a single species, well, it would be impressive due to its dimensions, but what is relevant here is that there are two species that coexist in the megacity: The curious thing is that both are solitary species and have never before been documented to form colonies. Furthermore, under normal conditions, the domestic tegenaria would hunt the Prinerigone vagansmuch smaller, but the researchers realized that both coexisted peacefully. Paradise. The reason? The total darkness may be inhibiting the spiders’ senses, allowing coexistence, but the toxic sulfuric environment may also be playing a role. What they are clear about is that the ecosystem is perfectly oiled: There is no photosynthesis as there is no light, so the microorganisms that are present are sulfur-oxidizing bacteriaconverting inorganic compounds into organic matter that sticks to the walls. There are chironomid larvae that feed on these biofilms. From the larvae, Tanytarsus albisutus emerge, mosquitoes that do not bite and that form dense swarms in an inland stream and of which there are an estimated 2.4 million individuals. By accident, they fall into the webs of the spider megacity and estimate that each spider touches 200 mosquitoes, so they are well fed, they do not need to hunt or leave the structure and they continue to expand the colony. The two species in love and company Implications. One of the researchers, István Urák, has commented that they often think they completely know a species “to the point that we think we understand everything about it, but even then unexpected discoveries can happen.” And he does not say this because the two species coexist, but because they have carried out DNA analyzes that have revealed that the populations of the Sulfur Cave are genetically different from their conspecifics that inhabit the surface. This means one thing: in the evolutionary line, those on the surface have gone one way and those in the cave have gone another, remaining isolated enough to evolve in another way and adapt specifically to the hostile environment they inhabit. These differences mean that microbial diversity is lower in cave spiders and females produce fewer eggs per sac than those on the surface, possibly because since they do not have predators, they do not have to produce as many offspring. a mine. Urák’s team is working on a follow-up study that may shed more light on these spiders, but in addition to the silk megacity, other teams have documented another thirty species of invertebrates that have adapted to this peculiar environment. Among them, another spider: the Metellina merianae who, unlike the other two, prefers to live in solitude. And, regardless of curiosity and even scientific interest, researchers have stressed the importance of protecting this colony. For this reason, the exact location of the cave has not been shared, but the situation is complex because it is located on the border between Albania and Greece and it remains to be seen which country has the power to protect it. In the end, they have been developed in a very specific way and any external element that is introduced can be a contaminant. Beyond the rejection that spiders produce for many of us, this discovery puts on the table that, even in conditions as hostile as a cave without light, with little oxygen and the presence of toxic gaseslife not only makes its way, but “enemy” species can form enormous communities that live in harmony. For the sake of the Prinerigone vagansmay there never be a lack of mosquitoes… Images | Marek Audy, Subterranean Biology In Xataka | We have genetically edited a spider to produce a fluorescent red web.

Australia has decided to make a contribution to the lunar race in the most Australian way possible: with a giant spider

The new lunar race does not consist only of returning to the moon, but to stay. And for that infrastructure is needed. NASA wants lunar concrete houses for 2040ESA has already found a method to pave roads from the regolitoand China trust that 3D impression accelerates your plans to create a large lunar base. Now an Australian company has put its own bet on the table, one that could not be more Australian: a Robot spider. A giant robot spider that prints houses. His name is Charlotte, and he is a hexapod robot (entomologists will forgive me) that displays his six legs to become a huge 3D printer capable of moving along the land as he built a house. Presented during the 76th International Congress of Astronautics in Sydney, this creation of Australian companies Crest Robotics and Earthbuilt Technology has been Designed for a double purpose: Solve the housing crisis on Earth and, incidentally, prepare to build the first bases on the moon, something that Australia could contribute as a partner of the Artemis program. Build at the speed of 100 masons. Although the most striking of Charlotte is the arthropod inspiration design, its true magic lies in the combination of advanced robotics with a very particular 3D printing system, which can have a key advantage on the moon. Instead of depending on massive porches, such as other 3D construction printers, Charlotte promises to place himself on the walls that he creates and walk with his six legs to move as he adds layers to the building. This gives it an agility and portability that traditional printers do not have. According to its creators, you can build A 200 square meter house in 24 hours, so it will work at the speed of 100 masons. On the moon the whole floor is concrete. On paper, Charlotte meets several of the requirements to manufacture on the moon: it is light, you can fold its legs to occupy much less space in a rocket, and is designed to collect the materials available locally. On Earth, it promises to manufacture houses with sand, earth or crushed brick. On the moon, the plan is to collect soil regolito, compress it in a flexible tank and use the compacted material to form the layers of walls with already tested 3D printing techniques. It is an industrial and automated version of the construction technique with sacks. The regolite, the fine and abrasive dust that covers the lunar surface, is both a problem and a solution. It was a nightmare for Apollo missions, adhering to costumes and equipment, but it is also The fundamental raw material For any lunar construction project. If one day there are people living on the moon, they may do so in houses built in the most Australian way: with a gigantic spider (forgiveness, hexapod) robot.

We have genetically edited a spider to produce a fluorescent red cloth. And the implications are promising

Mutant spiders. It could be the premise of a film that mixes science fiction and terror, or someone’s nightmare with Arachnophobia. However, the first mutant spiders created by the human being respond to something much more innocent. But maybe even more interesting. Mutant spiders. A group of researchers He has genetically edited A group of spiders. The most curious of the results obtained by this team is probably a group of spiders that, after the edition, are capable of weaving a red spider web fluorescent spider. It is about First experiment of genetic edition in spiders of which we have knowledge. For this, the team resorted to specimens of the American domestic spider (PARASTIDA TEPIDARIORUM), A species that, like many others, uses its spider web not only for hunting but also to protect its eggs. A fascinating material. Spider silk is one of the most interesting materials in the animal world. Spiders are capable of segregating different types of fabric and among them, structural silks are among the most remarkable for their very tangled resistance that binds to its elasticity, lightness and the fact that it is a biodegradable material, explains the team responsible for the study. CRISPR-CAS9. In its experiment, the team turned to the “scissors” of genetic edition CRISPR-CAS9. They began the process focusing on a gene linked to the development of the eyes with the aim of obtaining a first easy result to identify. The team injected his tool of genetic edition in a female in order to eliminate the gene chosen in their reproductive cells and thus be able to detect changes in their litter. The Resutlanted: Spiders who did not develop their eyes. From the eyes to the silk. The first success led to repeat the test, but this time focusing on the genes responsible for coding some of the proteins present in the structural silk of the spiders. In doing so, spiders wove spider silk filaments of fluorescent red spider. The details of the experiment were published In an article In the magazine ANGEWANDTE CHEMIE. A first step. To be able to edit the genes responsible for the production of a material as interesting as the structural filaments of spider fabrics opens new doors when it comes to knowing this material and its biochemical origins. Of course, we can also pave the way for being able to synthesize it efficiently or even in the development of materials with similar properties. “We have demonstrated, for the first time in the world, that (the tool) CRISPR-CAS9 can be used” to incorporate a desired sequence in spider silk proteins, thus allowing the functionalization of these silk fibers, ” stood out in a press release Thomas Scheibel, co -author of the study. “The ability to apply CRISPR genetic edition to spider silk is very promising for material science; for example, it can be used to increase the already high spider silk breakage.” In Xataka | ‘The Last of Us’ is already happening in the animal world and the last species in suffering are the “spiders of the caverns” Image | Patrick Edwin Moran / University of Bayreuth
