Two videos show how 80 people from a plane have saved life in the last plane crash. There is triple explanation

After the tragic accident last month Between an American Airlines plane and an United States army helicopter that left 67 dead, on Monday there was a similar scene when it occurred A forced landing of Delta Air Lines’s flight 4819 In Toronto. Two videos showed rawly the scene that the 80 people who went on board and who ended the plane turned. And yet, it did not end in tragedy. How could they be saved? The “miracle.” Delta Air Lines’s flight 4819, operated by Endeavor Air, made a seemingly normal landing at the Pearson International Airport in Toronto until, Suddenly, everything went wrong. As soon as the wheels began to touch the wheel, the plane slipped, hit its right wing, turned on its axis and ended upside down, leaving an absolute chaos scene. But as we said, and despite the violence of the accident, The 80 passengers and crew managed to survivealthough 18 were injured, including an adult and a child in critical condition, although already out of danger. The impact and the fight to escape. They counted at the Washington Post in a report report that the passengers described the impact as “collide with a wall” before the plane turned. When they were face down, many remained suspended by their seat belts, seeing how the fuel slid through the windows and the fire consumed part of the aircraft. Pete Carlson, a paramedic on board, managed to unbutch and drop to the roof of the planenow turned into the ground, before helping others free from their seats. Meanwhile, passengers, in shock, collaborated with each other to get out as quickly as possible. A video recorded by Pete Koukovanother passenger, showed the crew organizing the evacuation with firm and urgent instructions, guiding people through emergency doors in an inverted plane, a rare scenario in aerial accidents. Outside, firefighters sprayed fushes with foam, while black smoke and flames hindered visibility in full snowstorm. How tragedy was avoided. In front of many Other aerial catastrophes More or less recent, experts have been detailing these days how the “miracle” was possible. Actually and as we will see, there is not a single factor, but several that helped that finally there was not a single death. Three were the main factors that we describe. Plane design and safety measures. He Bombardier CRJ900like all modern commercial planes, it is built with standards called “Crashworthiness”which means that its structure, safety belts and seats are designed to maximize survival in case of impact. In this regard, the cabin absorbed much of the strength of the crash without disintegrating, allowing passengers to go alive. According to Graham Braithwaiteexpert in aeronautics at the University of Cranfield, these elements were fundamental for passengers to resist the impact of the overturn without fatal injuries. Professor Michael J. McCormickfrom the Embry-Riddle University, stood out in the post That engineering and aeronautical regulations have advanced so much that accidents that in the past would have been lethal can now result in total survival. Assessment of the crew. Equally important that the design of the aircraft was crew trainingdecisive to organize a rapid and effective evacuation. Despite confusion and chaos, they managed to maintain order and get everyone out of the plane in a matter of minutes, even with the aircraft dump. Here it is important to remember that the regulations of the Federal Aviation Administration (FAA) require that Any plane with more than 44 passengers can be evacuated in less than 90 seconds. However, in this case, the evacuation was more complex because the plane was overturned, hindering the orientation and exit of the passengers. Immediate response of emergency equipment. The third of the key legs. Toronto airport authorities acted rapidlyensuring the area and preventing the fire from extending to fuel deposits. The first air control reports confirmed the severity of the situation: “The plane is face down and in flames”, which led to a rapid mobilization of rescue equipment. According to the norms of the International Civil Aviation Organization (ICAO), rescue teams They must respond in less than two minutes. In this case, firefighters and paramedics arrived at the place in a matter of minutes, stifled the fire and helped evacuate passengers. Causes of the accident. Although the exact cause of the accident has not yet been determined, it is known that landing occurred under wind conditions up to 70 km/hyve accumulated On the track after two recent storms. Thus, the airport firefighters ruled out problems with the track, which suggests that other factors, such as mechanical failure or human error, could have influenced. Be that as it may, in a context where Recent air accidents They have resulted in fatal tragediesthe total survival of flight passengers 4819 is a real testimony of the advance in aeronautical engineering, security protocols and emergency response. Although The images of the airplane burned and overturned They suggest an inevitable disaster, the combination of these factors allowed to avoid the worst. As Carlson underlined In his interview, after leaving the plane I only thought about one thing: “I didn’t care about the cold, I didn’t care how much I had to walk, all we wanted to be out of the plane.” Image | Yyzbrennan In Xataka | The main suspect of the plane crash in South Korea is common in aviation.

Europe has the highest rate of multiple sclerosis in the world. The explanation lies in the DNA of the steppe shepherds

First there were hunter-gatherers about 45,000 years ago. The first modern humans arrived in a Europe where the Neanderthals still reigned. Then there were the farmers of the Middle East about 11,000 years ago and finally, about 5,000 years ago they were the nomadic pastoralists of the steppes of Central Asia. That is, according to research published in the journal Naturethe common genetic heritage of Europeans. A heritage that explains why, in an incredible historical twist, multiple sclerosis affects us more. A DNA mutating in the middle of the great steppe. While agriculture gained weight in the world, the great Eurasian steppe continued doing its thing. The culture yamnaa group of pastoral towns that arose in the enormous plains south of the Urals and east of the Black Sea, generations and generations passed living with livestock. Variant. It was there that it emerged (and was selected) a small genetic variant that strengthened natural immunity against zoonoses; that is, against livestock infections that could easily jump to the human communities that raised them. 5,000 years later, this genetic variant is behind the fact that Europeans have a higher risk of suffering from Multiple Sclerosis. The deep origins of current diseases. The study led by the Universities of Cambridge and Copenhagen (but with the participation of many more) analyze in detail from the DNA of almost 5,000 individuals spread throughout history. Some studied remains date back to about 34,000 years ago. The reconstruction. Reconstructing humanity’s immense genetic tree, researchers found numerous keys to understanding why there are specific geographic areas or ethnic groups that suffer from some diseases more than others. They realized that southern Europeanswith a greater genetic legacy from the agricultural people of the Middle East, have a greater predisposition to develop bipolar disorders; that people from the East had a higher genetic risk of developing Alzheimer’s or diabetes; and those from the northwest had a heightened risk of sclerosis. A medical enigma. For years, scientists have tried to understand why Europe has, with about 143 cases per 100,000 inhabitants, one of the highest incidence rates of sclerosis in the world. As I said in the previous paragraph, as you go south and east those differences fade, but (even so) the greater risk of developing this disease It is a European ‘differential fact’. Understanding better. The most interesting thing about all this is that the idea that the answer lies in the genetic history of its inhabitants It is not only a historical curiosity. On the contrary, thinking about this from an evolutionary point of view allows us to understand the disease in a new way.

Mobile phones have been stagnant for five years when it comes to innovation. There is an explanation

Mobile phones have not innovated for years. Or, at least, not too much. There was a time when jumping from one generation to another was a box of surprises. New designs, completely new features, and crazy innovations to surprise the public iteration after iteration. For a few years now, the meme of Smithers and the doll with the new hat has become more true than ever. The new phone will be the same as last year, with a little more power, a slightly better camera and AI features that we may never use. All this has a reason for being. The times of innovating are (almost) over. There was a time when manufacturers were not afraid to break the mold to create different devices. Samsung did it with the curved screen of the Galaxy Round, LG had a G Flex 2 self-healing, and Xiaomi dared with pop-up cameras from the body with the 9T Pro. There was a time when manufacturers dared to innovate. A few years ago, jumping from one generation to the next meant a significant leap. Going from a Galaxy S2 to an S4 was a brutal change. The same thing happened between LG G3 and the G5. It is true that the brands were taking some blind steps, completely changing the phone from one generation to another: there was not much consistency, but there were significant changes. Apple, which has always moved at its own pace, was one of the few that continued to maintain designs and advance specifications discreetly, without disruptive changes between generations. On Android, every year was an adventure. Being groundbreaking doesn’t work. The most innovative ones have not fared too well. LG ended up closing its mobile divisionNokia stopped inventing and started selling traditional, simple mobile phones under the HMD umbrella, and major manufacturers like Samsung, Xiaomi and Huawei began to make iterations that were increasingly similar to each other. No matter how many critical voices are heard against continuity, continuity works. Or so the data says. If we look at the list of best-selling devices in the world We found that, year after year, the iPhone and Galaxy (both mid-range and high-end) are the ones that repeat the podium year after year. Those phones that precisely “innovate” the least are the ones that sell the most. A path to refinement. The image you see above is a good example: it is even difficult to distinguish last year’s model from the new model. Manufacturers have changed the philosophy: if something works, don’t touch it. For approximately four years now, improvements between generations have been slight. Changes in the camera, small refinements in the design, updated processor, and some technologies such as WiFi, Bluetooth or USB that change protocols. The great innovations of these years have been camera buttons, longer telephoto lenses and the arrival of AI (which, no matter how much it is sold as a gimmick, plays a very secondary role in daily use). And it’s not a negative thing.. Smartphones are at a point of maximum maturity. So much so that it is difficult to think about how to improve them. Screens: we have as much resolution as practically that of a television. Very high peak brightnessand calibrations worthy of studio monitors. The big leaps will involve the implementation of matte screens and better drivers so that these panels are increasingly more efficient. Batteries: 2025 has been the key year for the implementation of carbon-silicon, bringing with it more capacity in a smaller size. 6,000 and 7,000mAh batteries are a realityguaranteeing two days of full use in many cases. There is still a way to go, but the great leap has already been made. Microprocessors: today mobile phones they are so powerful That, in many cases, this is a problem. We have not reached peak power, but we are at a point where a phone is capable of playing triple A games as if it were a console. Cameras: It is one of the points where there is the most room for improvement, but this does not happen through the hardware, but through the software. Formats: Manufacturers want to break with traditional formats, and that is why they are betting on form factors such as folding ones. These grow slowly, but they represent just 1% of total sales. Again, innovation does not sweep. We are far from the real peak. We have been thinking for years that we are approaching the peak smartphoneto that point of no return where it will be practically impossible to improve what we already have. We are right in our approach: progress is becoming less and less and, to appreciate it, it is necessary to be more and more thorough. Despite this, progress is present and, although they are minor changes, they are there. Your 2025 mobile has a processor that allows it to run the applications with the best performance. The quality of its microphones is getting better and better, its fast charging system is very far from those 2/3 hours necessary to charge your old phone and, in short, if we look back 3 or 4 years, the advances are still present, for small as they seem.
