In Ukraine we had seen armored vehicles from Mad Max, but the latest Russian invention has left everyone speechless: assault “hedgehogs”

by

Last June, several images captured by reconnaissance drones of the Ukrainian forces sighted a unprecedented Russian offensive: Waves of two-wheeled troops launching motorcycle charges to break the kyiv front. If the scene seemed like a still from Mad Max, shortly after it would become reality with the appearance of trucks that we saw in the movie. The latest: in an unprecedented turn of the screw, Moscow has brought out its assault “hedgehogs” The tank turned into a “hedgehog”. The recent appearance of a T-80BVM Russian equipped with an extreme structure of steel cables along with foliage and tree branches, described as an “assault hedgehog”offers a revealing picture of the state of mechanized warfare in Ukraine. The photographs, broadcast by the channel Vodohray Telegramshow a T-80BVM with an anti-mine roller TMT-K and a T-72B3 with a KMT-7, both wrapped in dense cable cages covering the chassis, tower and top. On the T-80BVM, in addition, a electronic warfare system. This modification, primarily intended to thwart FPV drone attacks, represents the rapid adaptation of the battlefield to a threat that has completely altered the relationship between armor, mobility and survivability. And more. The structures that are seen look for prevent direct impact or cause drones to become trapped or damaged before reaching vulnerable points. However, the additional protection noticeably increases weightvolume and operational complexity: tanks become slower, more visible and difficult to maneuver in urban or forested areas. Still, the fact that these modifications arise not only from field improvisations but also from organized units highlights the extent to which drone warfare is redefining the very form of ground combat. T-80BV in the Kubinka tank museum Evolution of the T-80BVM. He original T-80developed in the late 1970s, was conceived as an elite tank capable of combining firepower with exceptional mobility thanks to its gas turbine engine. This feature made it faster and quieter than other Soviet models, which made it a symbol of military modernity in its time. With the dissolution of the USSR, many T-80s were stored, but the version T-80BVM (introduced in the 2010s) introduced important improvements: Relikt reactive shieldingmore modern optical and thermal systems, and mechanical adjustments to increase reliability, especially in cold environments. In Ukraine, where a war of attrition is being fought with very dynamic fronts, the T-80BVM has been used like crash car for quick attacks or penetration maneuvers, but the proliferation of drones has reduced their safety margins, forcing the modification of even a tank originally designed to move quickly and freely. Other armor seen in Ukraine FPV and the collapse of the classics. The expansion of FPV drones (capable of attacking from above or vulnerable flanks) has generated a conceptual crisis for traditional armor. Tower ledges, engine cover and commander’s hatch hinge have become critical points that even a cheap drone can exploit with an improvised payload. For this reason, both Russia and Ukraine have experimented with “cages”“mobile bunkers” and supplementary armor. It turns out that the first versions of these cages, superficial or with rigid bars, were insufficient: the drones learned to maneuver between gaps or detonate just above them. Hence the cable structures They represent a more advanced iteration of that improvised defense: they are more flexible, denser, and more likely to entangle or slow down small aircraft. However, its effectiveness is uneven, depending on the quality of the wiring, the speed of the drone and the ability of the FPV operator to manually adjust its trajectory. Camouflages and protections. we have gone counting before. The war has generated enormous tactical creativity on both sides. They have been seen covered armored of thermal networks to confuse infrared cameras, coated vehicles of tires to absorb shock waves, camouflaged transport with awnings and scrap metal to break silhouettes and even towers protected by improvisations of beams and bars that are reminiscent of shed roofs. Some of these designs seek to deceive reconnaissance drones, others intend just gain seconds before the impact of an FPV, a time that can allow the crew to abort, retreat or request cover. Each innovation introduces new countermeasures: when the cages appeareddrones began to carry loads at an angle, and when jammers appeared, wired drones or drones with more autonomous guidance systems began to be seen. War, in this sense, has become a constant laboratory where adaptation is measured in hours, not years. Uncertainty. Having said all this, the image of the “steel hedgehog” around the T-80BVM is not only curious: it symbolizes a war in which the rules of armored combat are changing at great speed. Tanks are still valuable, but can no longer operate without a dense layer electronic supportinfantry cover and constant surveillance of the nearby sky. The question that emerges is whether these adaptations keep the car useful or whether they represent an attempt to keep a car alive. concept in transformation. For now, the response on the front is pragmatic: any measure that allows us to survive one more mission is welcome, even if it turns a vehicle designed for speed and direct impact into a slow, heavy creature covered in metallic thorns. Because in the war in Ukraine, survival has become the true armor. Image | Telegram, Alan Wilson, ArmyInform In Xataka | An imperceptible hum is wreaking havoc in Ukraine.

thermal lurches have weeks left

Suddenly and without warning, the cold has crept into Spain. More than half the country is waking up with temperatures close to zero And, although it is true that the afternoons are still mild, millions of people are faced with the big question of the moment: is it time to change clothes? Or what is the same, translated into meteorological terms, is the cold here to stay? What has happened? In reality, it is not so much what has happened, but what is happening and what is going to happen. Because in the coming days, we are going to see very rapid temperature jumps (“from ice to sun in 48 hours“, with increases and subsequent decreases). We have already seen it: Ciudad Real went from a minimum of 13 to a minimum of 5 from one day to the next. Teruel, Salamanca or Palencia dropped below zero degrees. And, although in the abstract it is not strange that as we approach November the days are increasingly colder, the heat is holding so much so that the “saw teeth” are much more pronounced. Temperature changes are so marked that they are no longer just meteorological curiosities: they are causing problems in people’s daily lives. Is it going to continue like this? This is interesting. According to AEMETNovember is going to be relatively warm at least during the first fortnight. Warm anomalies and above-average precipitation. However, the ECMWF suggests That’s where the “heat” ends. To that first fortnight with thermal values ​​still above average and strong Atlantic circulation (i.e., more generous rainfall on the western slope); It seems that a second half of November will follow in which a possible pattern change will bring more normalized temperatures. Because? On a technical level, what we are seeing is the product of an alternation of warm ridges and cold fronts. We are talking about mild days, open skies and thermal rises, followed by abrupt drops as cooler maritime air enters. What does all this translate into? In a very pronounced thermal variability. That is to say, a heightened risk of isolated frosts in the interior despite the fact that the days are mild and pleasant. This will have strong impacts in agriculture (especially stone fruits and autumn products), in energy demand (at such an uncertain time) and health (the early arrival of respiratory infections). All this punctuated by a series of Atlantic storms that will repeatedly impact the west; while the Mediterranean will be relatively calm with probable scares against DANAs or undulations of the jet stream. So, is the cold here to stay? In the short term, no. The models point to a soft first half of November compared to the average, with occasional declines. The stable cold seems to be delayed until the second half of November. Image | Tomer Burg In Xataka | A group of researchers is trapped in an Antarctic base under a threat: that of one of them.

has left Bizum, dataphones and even ATMs out of the game

by

The cloud of Amazon Web Services has suffered a crash in one of its data centers that is affected by a multitude of services worldwide. Alexa, Fortnite, Perplexity, Canva, Roblox… the list is enormous, but it doesn’t stop there. The fall is also making it impossible to pay with a credit card in many stores, through Bizum or even to withdraw money from the ATM. Dataphones. The consequences of the fall of Amazon Web Services are preventing both physical and online purchases. Many businesses are experiencing problems with dataphones because The fall has affected Redsyswhich is the main POS platform in Spain. It is also used on many websites, so it is affecting online payments on many websites such as Tickermaster. Nor take money. Given the problem of dataphones, many people have gone to their bank for cash to be able to pay. This is what our colleague Alberto did, only to find that the ATMs at his bank (BBVA) were not working either. It is not the only bank affected, there have also been failures in ATMs at Unicaja, Bankinter and other entities. Bizum. The Bizum payment service also does not work for many users. At Xataka we have verified that it fails in Sabadell, BBVA, Santander, Revolut and in X there are more users reporting bugs. When the dataphones failed, those who did not have cash tried to pay through Bizum but found that it did not work either. In addition, some banking apps are failing, so in many cases it is not even possible to check if Bizum works. A curiosity: the Santander app gives an error when entering with FaceID on an iPhone, but it let us enter using the code. Irregular. It has not affected everyone or all banks equally. Some ATMs have already been restored and there have been stores where it has been possible to pay without problem or after a couple of attempts, why? Sources from the banking sector have confirmed to Xataka that the AWS failure is being restored, but it takes time for the changes to reach the entire network. In the same way that the solution takes time to deploy, the error did not spread at the same speed, which is why both the impact and the subsequent restoration are being irregular. In development…

A hero without a cape recorded the same shot for a year. Along the way he left the flat earthers without arguments

by

Intrigued by the phenomenon, Eratosthenes decided make an observation in Alexandria, located about 800 kilometers north of Siena. There, on the same day and at the same time, he noticed that a vertical stick did cast a definite shadow. The discrepancy led him to a fundamental question: how was it possible that in one place there was no shadow and in another there was, at the same time? Eratosthenes deduced that the only explanation was that the earth’s surface was curved. A lot of time has passed since then, but the flat earthers are still among us. The home experiment. For centuries, the idea of ​​a flat Earth has outlived telescopes, satellites and lunar missions. Despite the overwhelming evidence, from the images taken from space and the established physical principles from Aristotleflat earthers have continued searching for the edge of the planet, organizing expeditions to Antarctica or navigations to the supposed “end of the world” that invariably end with the same discovery: that the edge does not exist. Be that as it may, an anonymous Reddit user has dismantled once again his entire creed without leaving home. Armed only with a security camera, the shadow of his garage and the patience of an entire year, he managed to record a test as simple as it was incontestable: the movement of the Sun drawing a figure of eight perfect on the ground. The footprint of the Sun. Between March 2024 and March 2025, this user (under the alias RedditorofReddit07) marked daily, at the same time, the position of the end of a shadow cast by a corner of his garage. After twelve months, the yellow dots traced on the cement an asymmetric curve in the form of infinity: an analemma. This phenomenon, documented by astronomers for centuriesis the direct result of the 23.5 degree tilt of the Earth’s axis and the planet’s elliptical orbit around the sun. In the summer months, the star reaches the highest point of the analemma; in winter, the lowest; and during the intermediate seasons the rest of the figure is drawn. Each latitude generates a slightly different shape, but they all share the same essence: an Earth that moves, rotates and tilts, not a motionless disk under a celestial lantern. The physics of time. The analemma not only reveals the movement of the planet, but also the difference between solar time and time measured by clocks. In theory, noon always occurs at 12 o’clock, but the Sun does not reach its highest point at exactly the same time every day. This variation, a consequence of the inclined axis and the unequal speed with which the Earth travels its orbit, is the reason why the analemma adopts a figure-eight shape. Science sums it up in a formula called the “Equation of Time,” an adjustment that explains why solar days vary in length and why the apparent position of the Sun advances or lags throughout the year. This mismatch is as predictable as it is beautiful, and can only be explained by a spherical planet that orbit a starnot by a flat disk with a wandering Sun that rises and falls without altering its size. The impossible refutation. In the flat earth modelsthe Sun moves on a plane, like a lamp on a table, projecting its light in circles on the surface. If that were true, the end of a shadow always observed at the same time should remain fixed throughout the year. However, the garage experiment shows exactly the opposite: a harmonic displacement that only fits the heliocentric model. Reproducing this effect in a flat world would require, in addition to an act of faith without a network, that the Sun change its trajectory, height and speed in an absurd way, violating the very laws of optics and gravity that its alternative model allows. The flat earthers themselves, faced with such evidence, barely manage to develop new explanations that are more imaginative than scientific. The method. He merit of the experiment It lies not in its complexity, but rather in its humility. Without telescopes or laboratories, a simple fixed camera and a daily routine were enough to record the annual dance of the Earth in front of the Sun. Each shadow point marked on the cement is a slap to the conspiratorial noise that floods the internet. In times when science is forced to defend the obvious, an ordinary garage has become an observatory and an anonymous user a popularizer. He already said it Carl Sagan himselfalthough he only needed a stick to dismantle conspiracies. Image | reddit, jailbird In Xataka | 48 people went to Antarctica to prove that the Earth is flat.

When the Titan submarine exploded there was nothing left to rescue. Except one very important thing: a memory card

by

It has been more than two years since the Titan submarine tragedy and the story continues to make people talk. The last thing we know is that the recovery teams found the camera that was part of the submarine. The camera was damaged, but inside it housed a memory card from which they were able to extract image and video files, although none from the implosion. The discovery. Youtuber Scott Manley told it in your X account. In a series of posts, Manley has published several images of the camera’s recovery report detailing its characteristics and condition. It was a Rayfin Mk2 Benthic underwater cameracapable of submerging up to 6,000 meters deep thanks to its titanium body. Although the case appeared intact, the sapphire crystal lens was shattered. Upon disassembly, many of the components had light damage, but one of the boards included an SD card that was in good condition. The content of the card. Investigators and forensics managed to make a duplicate of the card and extract the contents. In total, they obtained nine images and twelve videos. However, the camera had been configured to save the captures on an external storage device, so it did not contain any images from the day of the fateful dive, but rather they were images taken at the Marine Institute in Newfoundland, which was where the missions to the Titanic departed. In the images they have shared you can see the facilities and some underwater images, but at shallow depths. Catastrophic implosion. The Titan left Newfoundland on June 16, 2023. An hour and 45 minutes had passed when communication was lost, but it was not until four days later that the coast guard found the first remains of the vehicle and confirmed what they suspected: it had imploded. They found remains of the vehicle, but no body of the five crew members could be found. It was avoidable. The Titanic is located at a depth of 3,800 meters, where the pressure is 380 atmospheres. There is vehicles capable of reaching this depth and even more, but the Titan had a long history of problems and his own Former director of operations called the tragedy avoidable. In fact, several members of the underwater exploration community, including James Cameron, They had written a letter to OceanGate where they expressed their concern and assured that they were “going down the path of catastrophe.” The company ceased its activity after the accident.

The tremendous hole that the Olympic Games have left to Paris

by

When they ended The Olympics of Paris last year there was something that did not end: the National Debateextensible to many other games in other planet enclaves, about its true legacy. For critics with the event, the Supreme Audit Institution of France has just given them all the world’s gasoline, one in the form of a devastating economic report. The real weight of the games. As we said, the Courtes Cours has reviewed Uploaded the public cost of the Olympic and Paralympic Games of Paris 2024, encrypting the contribution of the State and the territorial collectivities In 6,650 million eurosthat is, about 700 million more than expected in June. In its report presented to Parliament, the Rue Cambon institution details that the updated figures include both the expenditure on the organization, that amounted to 3,020 million (With a very high weight of security), such as infrastructure destined, which reached 3,630 million, first incorporating the disbursements of local authorities and works to guarantee the use of SENA, estimated at 331 million. In spite of certain cost overrun surplus of 75.7 millionwhich avoided resorting to the state guarantee. Comparison with other editions. The Cour holds that Paris games were almost Twice less Regarding costs for public coffers that, for example, those of London 2012, although it alerts on the security chapter, whose infrapreting was remarkable: compared to the 200 million calculated in the candidacy dose, the real expense amounted to 1,440 million. This deviation, far superior to that provided for in the 2024 Finance Law, constitutes the main reason for concern indicated by the magistrates. “Modest” impact. He Report Introduce This time an evaluation of the public income associated with the event, which total 293.6 million euros coming from fiscal collection, the special transportation of transport and advertising sales of France Télévisions. However, these figures must be corrected by Fiscal exemptions (57 million, as in the case of Omega sponsor) and for the so -called “eviction” effect on sectors such as tourism. Cour concludes that the impact on the economy was limited: just 0.07 % of GDP In 2024, compared to 0.25 % estimated by INSE for the third quarter of that year. Beyond the short term, it insists that it is premature to assess the effects in the medium and long term. Debate and criticism. Le Monde told that the Methodology of the Cour has generated friction with the Olympic responsible. The Cojop reproaches that The report It has included expenses that do not consider directly linked to games, such as subway prolongations, burial of electric lines or cost overruns of the renewal of the Grand Palais, as well as the construction of schools. Also questions that they were not taken into account The amortization nor the proportionality in the use of shared infrastructure. According to Tony Estuet, president of the Organizing Committee, the real public cost did not exceed 2.5 billionso he denounces problems of rigor and a systematic bias against the project. The debate about the legacy. One of the central points of the controversy is the tangible inheritance of Paris 2024. While the Government defends that investment in transport, housing and the Decontamination of SENA They represent lasting improvements, social groups denounce phenomena of gentrification, eviction and a “social makeup” that benefits the international image of France more than its most vulnerable citizens. The Cour too He raised doubts on the true capacity of these investments to transform urban life in the Parisian region. A historical ballast. The debate on Paris 2024 is inserted in a long tradition of games that end up being financial watchmaking bombs For host cities. From Montreal 1976, which took three decades to pay A monumental debtuntil Athens 2004, often cited as one of the factors that They worsened the crisis Greek financial, Olympic venues have experienced chronic cost overruns. The reason? The committees They usually inflate calculations Return of investment in the candidacy phase, presenting optimistic projections that rarely materialize. The case of London 2012 showed that even when the games are presented as “reasonable”, the budget weight It ends up duplicating The initial forecasts. The COI crisis. Plus: The International Olympic Committee has been going through a Crisis of legitimacy and headquarters. Less and fewer cities are willing to assume the associated financial and political risks: Los Angeles 2028 was awarded without competition After the withdrawal of other candidacies, and the last winter edition in Beijing 2022 had to be held In artificial facilities In full desert, an example of the anomalies facing the organization. Cortina-Milán 2026 too It has been questioned by APPROVESlogistics improvisations and political tensions between regions and central government. In this context, Paris 2024 reflects both the symbolic greatness and the structural fragility of an increasingly difficult Olympic model to sustain. Success with doubts. If you want, immediately, Paris 2024 has been considered an organizational and sports triumph, projecting that image of France as a country capable of hosting a global first -order event. In fact, both Cour and Cojop They have seen In Paris’s experience, a model to consider the Olympic Games of Winter of 2030 In the French Alps, to which They will be allocated Six of your seven recommendations. However, the debate about its true financial and social legacy is far from closing. French experience feedsIn addition, an argument that crosses borders about the future of games: if they will continue to be an aspiration for cities or simply a risk that most will prefer to avoid.

There is an open debate about sports motorcycles and the DGT has not been left out

by

The motorcycles have become the last refuge of the maximum sportiness expression that we can see in the streets. Faced with increasingly heavy cars and monitored by the European Union, motorcycles continue to maintain low weight maximum (relatively), stratospheric acceleration and tip speeds that take away the hypo. And, of course, there is an open debate. “With head”. The statement is the renowned Italian pilot and journalist Nico Cereghini who pointed in the Italian media Moto.it That “as bikers, if we only thought with head, today we would all be with 20 or 30 hp of maximum power under the back.” Then he points out: “But every passion has little rational, as is known. Emotions are sought, they are chosen with the stomach and with the heart.” In his column, Cereghini says that it will not be the users who opt for rationality, so he wonders if manufacturers should not “take care of establishing limits, before the legislator does it in their place.” “They are very busy packaging dreams, deceiving the consumer that they can run very fast, it is not known where or when.” A debate that is not new. Cereghini’s reflection is striking for his weight in the public debate of motorcycling but is not new. In the 90ssports motorcycles were completely dismembered with maximum infarction speeds that exceeded 300 km/h. The most striking were Japanese motorcycles, excessive powers and an electronics that almost shone due to its absence. Aware that this could be a problem and that they began to enter a crazy race to reach 400 km/h on a street motorcycle, someone decided to put some sanity and A gentlemen’s pact was signed To limit power … at 299 km/h. The DGT has its opinion. And, of course, it is not very close to that of speed fans. Pere Navarro, director of the DGT, I already pointed out last year that “a 200 -horsepower motorcycle with 200 kilos is Made for the circuit and on the road it has a special danger, everyone has to be aware of it. “ From there, the bulles shot up. As usual with the DGT, social networks were filled with comments ensuring that traffic was going to ban this type of motorcycles but as they remembered in Motorpasion motorcyclethere was nothing on the table and, in fact, they cannot make this decision for themselves. Has any measure been taken? These motorcycles with a supercar power weight have always been in the spotlight but almost surprising that, seeing the efforts that have been taken by self -limiting cars in Europe with a Arsenal of ADAS systemsthe focus on this type of machines has been minimal. Already in 2008Pere Navarro made statements in which he was favorable to apply a limitation to 100 hp for motorcycles. This proposal was studied in the European Parliament at the request of France, which already applied the measure, but did not go ahead. The French exception. In France, Motorcycles have been limited to 100 hp between 1985 and 2016. In the 80s it was considered that this 100 hp barrier should not be overcome, establishing a red line that they considered too dangerous. Then the market was saturated with motorcycles between 50 and 70 hp and safety among motorists was minimal. In 1995, Europe decides that countries that want to take advantage of this limitation are in their right to do so but only France follows this path. After many debates and resources, the European Union established in 2012 a New regulation for motorcycles and eliminates the French exception that rises in 2016 by European mandate. An anachronistic situation. The world of yield represents something almost exceptional right now. We could say that it almost seems anachronistic that a motorist can reach infarction speeds when damage is usually much more serious in a motorcycle accident than in the car for obvious issues. Of course, the European Union has done everything possible to limit the latter. But it is not only a matter of regulations. Among cars manufacturers too They begin to be common Limitations at increasingly low speed. Good for technical reasons (electric car) or claiming security reasons (like Volvo) But it is evident that speed begins to see with bad eyes. With such bad eyes that even in Germany There are more and more favorable voices to the limitation of speed in the mythical autobahn.

We believed that astronauts from the Apollo missions left the earth. Actually, they did not completely abandon the atmosphere

by

The idea that space begins where heaven ceases to be blue is a story for children. Decades of scientific research show that the Earth’s atmosphere It is much bigger than it was believed. Not even the 12 people who stepped on the moon abandoned at all their influence. Where the earth ends. As Explain the expert in heliophysics From NASA, Doug Rowland, there is no clear border. “The atmosphere does not stop at Everest, or where the planes fly. It continues and continues, becoming less and less dense as you go up.” The International Space Station, which orbits our planet about 400 kilometers high, experiences sufficient air resistance to need a periodic impulse. Otherwise, it would fall back to earth. But the real surprise came after Decades of Observations of Soho (Solar and Heliospheric Observatory), a joint mission of ESA and NASA. To the moon and beyond. A study Based on data from the Soho Observatory, he revealed that the outermost layer of our atmosphere, a faint cloud of hydrogen atoms called Geocorona, extends up to 630,000 kilometers, almost twice the distance from the earth to the moon. When astronauts from the Apollo 16 mission installed the first telescope on the moon in 1972, they captured an image of the geocorone shining in ultraviolet light. What they didn’t know was that they were still inside her. In words of Igor Baliukinmain author of the study: “The moon flies through the atmosphere of the earth.” Oxygen on the moon. The presence of the earth on the moon is not limited to hydrogen. Earth oxygen also arrives at our satellite. It occurs for about five days a month, when the moon passes through the Magnetocola of the Earth, the magnetic tail of our planet. Every time it happens, Oxygen ions are accelerated to the satellite and are embedded in the lunar soil. Researchers believe that this process has occurring 2.4 billion years, which means that lunar regolite could keep a record of the evolution of our own atmosphere. The “official” border of space. The Atmosphere is divided into layers: Trophosphere, stratosphere, mesosphere, termosfera and exosphere. The latter, the exosphere, starts about 700 kilometers high and merges with the solar wind about 10,000 kilometers. But their particles are so scarce and so scattered that they can escape towards space. The “official” border of the space is, by convention, the line of karm, located 100 kilometers from altitude. It is considered the point at which traditional aeronautics is no longer possible due to lack of air. However, the geocorone, the luminous part of the exosphere, is the proof that the atmospheric influence of our planet comes much, much further.
