“prehistoric fish with armored teeth does not exist, it cannot harm you.” The prehistoric fish with armored teeth:

“If you had been in Cleveland 360 million years ago, you would be swimming for your life,” said Rachael Funnel a few days ago and the truth is that he is absolutely right in the world. Not only because, at that time, the area in which the North American city is located was a shallow ocean, but because in those waters there was an exceptionally bizarre bug. Welcome to the world of Dunkleosteus terrelli. The fact that? In essence, a predator measuring more than four meters very different from any fish alive today. Although, to tell the truth, they were also different from any fish from 360 million years ago. And why are we talking about this now? Because it was just published a study in Anatomical Record in which the best preserved remains of the species (preserved for millions of years in layers of black shale) have been analyzed. And honestly, what they found is a little scary. They have been able to analyze in detail the bone plates that ‘armored’ the head and trunk of these fish. Furthermore, by analyzing muscle inserts and bone canals, they have unraveled the functional characteristics of the jaw, showing that, in short, we are facing a terrible predator. But ‘terrible’ in the literal sense. To begin with, because D. Terrelli It did not have teeth in the conventional sense: they had large blades of bone that worked with enormous blades that captured and tore apart everything they caught. To continue, because it is one of the first examples of the existence of a specific jaw muscle. The science of sea monsters. He Dunkleosteus terrelli is not news to us: “the last important work that examined in detail the mandibular anatomy of Dunkleosteus was published in 1932, when the anatomy of arthrodirans was still little known”, remembered Russell Engelmanprincipal investigator. For years (for decades!), we have been content to put bones back together correctly and that has prevented us from fully understanding what was happening. For example, not understanding the functionality of these creatures has prevented us from understanding many fundamental characteristics of sharks from an evolutionary point of view. In the end, behind all those bone plates, there was a huge amount of cartilage. That is to say, once again, the world of monsters hides many interesting things to understand natural history. Something that, although it may not seem like it, we still need. Image | Nell Conway In Xataka | We have found two prehistoric sea monsters in the largest cave in the world after 325 million years

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

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.

Protect Trump is a headache, so the secret service has bought a armored golf car: the Golf Force One

That Donald Trump likes golf is not a secret. It spends many hours in some of the fields that its organization continues to manage and, in fact, this sport was A throwing weapon in one of the presidential debates against Biden. It is not uncommon to see the current president driving his golf car, but recently he has seen him with something … strange: a golf car that It looks like the Batmobo And that he has already been nicknamed as ‘golf force one’ in allusion to the imposing Air Force One, the presidential plane. And, contrary to what we can think of first, it is not an eccentricity. The ‘Golf Force One’. A few days ago you could see a curious stamp in the Trump Turnberry field in Scotland, owned by … Trump. The tycoon was about to throw some holes with his son Eric when an army of the typical golf cars was seen accompanying another much more peculiar. It is the one you can see in the following image and that the press soon called ‘Golf Force One’. The minibesty that accompanied Trump In the field a security team formed by controllers for all who wanted to access, as well as different snipers stationed in strategic sites was deployed. Trump was in a conventional car, but this vehicle was followed closely that, as different police sources, affirmed the environment The TelegraphIt was a armored golf buggy. The minibesty. Part of the president of a country is the armored car. In the displacements, the authorities use them as a security component, and if you are Putin, Kim Yong Un (Apart from the car, has a armored train) or the president of the United States, it is evident that you need a armored car. The beast is the presidential armored cara mole that has all types of shields, but also active defensive systems that seem taken from a spy tape. And, obviously, comparisons with Buggy have recently seen there. The vehicle has been identified as a Polaris Ranger xa UTV (‘Utility Task Vehicle’, for its acronym in English), which is basically a robust buggy designed to transport loads on difficult terrain, with traction that is usually 4×4 and with safety systems such as antivuelco cages. Now, this ‘Golf Force One’ is not a Ranger X as it comes out of the factory, but one modified with equipment that is kept secret, but that includes a closed cabin and, at least on the front, a armored windshield. There are no more details, although a White House spokesman confirmed The War Zone that it is a new addition to the presidential fleet of special vehicles. Priorities. Polaris Ranger are not new in US authorities. The base version is sold for $ 20,000 (although Trump’s must cost a lot, much more due to that armor pack) and have been seen in border patrol tasks. Returning to the golf course, he saw the president driving his ‘cart’, but the ‘Golf Force One’ followed him closely. And it is something that is not only logical, but also necessary. In the golf courses there is a very strict regulation on vehicles that can circulate on the grass, since too much weight can ruin it. A armored glass is not particularly light, but a reinforced UTV is still weighing less than the beast and its nine tons. Follow it closely while Trump moves in his conventional car makes sense for a rapid extraction maneuver for any danger, and it is a safety measure more in an environment than It is a headache For your entourage of bodyguards. Polaris models to patrol the border It makes … meaning. A golf course, however private it is, is a huge open space, turning the players into very simple whites. In July 2024, the attempted murder during a rally held in Pennsylvania He went down in history For the powerful photographs that were captured and what resonated worldwide, but although it did not make so much noise, in September of that same year there was a second attempt. While the future president played at the Trump International Golf Club in Florida, another of his fields, an agent of the Secret service He saw something suspicious near the fence of one of the holes: a overshadowed face and the barrel of a rifle. The alleged shooter was caught And he is in prison waiting for trial, evidencing what we comment: a golf course makes you an easy target … and a armored buggy can be a good way to protect the president. In the end, beyond that it is a vehicle with all the meaning, Trump’s picture driving his car while the ‘golf Force One’ and a retahla of conventional buggys follow it is … curious.

The last to get to the China parade was Kim Jong Un. Because in North Korea the leaders do not fly, but they travel armored

Where is Kim Yong Un? The question shortly before the beginning of the Military Parade in Beijing For the 80th anniversary of victory over Japan and the end of World War II, it began to circulate among the attendees. The answer would come shortly after. Just because The missiles that North Korea He had shown hours before they fly at a vertiginous speed, the nation leaders do it slow and on land, but completely safe. A trip loaded with symbolism. The displacement of Kim Jong-un a Beijing represented much more than a simple transfer: it was his reappearance in the multilateral scene accompanied by an emblem of dynastic power, the known armored train as “the sun” (Taeyangcho). This convoy, painted green off and armored in each of its wagons, has been the means of favorite transport of the Kim family from the Foundation of North Korea, linked to both the personal security of the leader and the propaganda staging of the dynasty. Its use reinforced the continuity narrativetradition and strength in an event where state leaders of more than 20 countries coincided, including strategic allies such as Russia and Iran. The rail legacy. The train predilection comes from afar. Kim Il-Sung used it as Modernity symbol and closeness to the people, and Kim Jong-il made him Your exclusive vehicle for fear of flying, reaching a journey of thousands of kilometers Until Moscow in 2001. His trips were long expeditions in which the train became a residence, command room and meeting space with foreign leaders. After his death in 2011, occurred precisely on this train, one of his wagons was converted in exposed relic In his mausoleum in Pyongyang, consolidating the image of the railroad as an essential part of the cult of personality. Kim Jong-UN has continued tradition, although it combines the train with rented aircraft when travel demands to cross oceans, as happened at its summit With Donald Trump in Singapore In 2018. A armored office. Beyond tradition, the train is today an authentic Mobile Command Center. Their wagons have offices, meeting rooms, sofas, satellite communication systems, televisions and computers, in addition to a permanent bodyguard and medical staff. Security measures include Comprehensive armor and weapons Heavy on board, in addition to space to transport the leader’s own car. This infrastructure makes it an Rself -sufficient and safe efugiobut also in an extremely slow medium: its maximum round speed 60 km/hwhich, together with the precarious state of the North Korean roads, prolongs any journey for days. Thus, in 2019 he needed almost three days to reach Hanói from Pyongyang in his meeting with Trump. Luxury and ostentation. The train not only guarantees protection and functionality, it is also the scene of the excesses associated with the dynasty. For example, during the trips of Kim Jong-il, I They served live lobsters and delicacies of various international kitchens, while French wines arrived in air cargoes along the journey. They even organized shows on board with singers and actors to liven up displacements. Although similar anecdotes have not been documented in the era of Kim Jong-UN, South Korean intelligence services believe that the leader has inherited his father’s inclination by the Refined gastronomy and the ostentation. The train as a metaphor. So, “The Sun” It is much more than a vehicle: it symbolizes the rigidity of power that moves slowly, but with Absolute armorwrapped in luxury for the leader and sacrifice for the people. In each international trip, the image of the green convoy touring borders becomes a metaphor for the survival of an isolated regime, which combines tradition, ostentation and fear in equal doses. Kim Jong’s arrival a Beijing in this kind of strength about Raíles not only evoked his father and grandfather’s legacy, but sent the world a continuity message: The dynasty remains firm, armored against external threats and determined to maintain its rituals even in the era of hypersonic missiles and autonomous drones.

The Mossos have already armored the area

The Mossos d’Esquadra have intensified the controls In the immediate vicinity of the Barcelona airport after detecting that 70% of the parking companies operating in the area are irregular. These ghost companies scam travelers offering prices up to four times cheaper than legal competition, but vehicles return in poor condition or even use them to commit crimes. The magnitude of the problem. Between 25 and 30 irregular companies currently proliferate around El Prat, according to They have found The Mossos d’Esquadra. These companies capture customers directly in the terminals and offer their services for just 20 euros per week, compared to the 80 euros on average charged by legal companies. Of course, the price difference is irresistible for many travelers, but the risk of something in the vehicle intensifies. How Ghost Companies act. Unlike legal companies, which have their own facilities and shuttle services from specific points, these irregular companies operate exclusively at street level. “Legal companies have facilities from which they offer a shuttle between the terminal and a specific parking lot, but the irregular ones do not specify the parking point,” Explain in the middle of the country the sub -inspector of the Mossos in charge of the case. Actually, vehicles leave in shopping, industrial polygons or even on public roads. The consequences for customers. The cases documented by the police are worrisome. Some travelers have recovered their cars with thousands of additional kilometers, obvious damage or in unfortunate conditions. The most serious case registered was that of a woman who received a judicial notification For a robbery with violence committed in Martorell with her vehicle, while she believed that the car was at the airport. The Mossos confirmed that the vehicle had been used by the employees of the irregular company to commit the crime. The police response. THE FIRST GREAT OPERATIVE It took place on July 30with the participation of Mossos d’Esquadra, National Police and Labor Inspection. The result: 25 people identified, four arrested for infractions of the Foreigner Law and eight files open for serious infractions. In one of the inspected vehicles they located almost a hundred car keys in the glove compartment, and detected employees without driving or employment contract. A long -term strategy. “We cannot say how or when we will act because we do not want them to have any perception of when the controls will be done. The operation of July 30 made us see that it could not be a surgical intervention because it is a problem that has been enchanted,” assured the sub -inspector responsible for the environment. The Mossos have established a permanent device with morning, afternoon and night to act as a deterrent, especially during the airport activity peaks. The challenge of the complaint. Police recognize that the monitoring of these activities is complex because most affected do not present formal complaints. When they do, they are usually more than criminal administrative claims. At the moment, only three cases are being investigated as possible criminal crimes, being an example of the difficulty in pursuing these practices at the judicial level.
