A paleontologist discovered a frozen bison for 50,000 years. Then he stewed him to eat it with vegetables

Almost half a century ago, in the middle of the Summer of 1979the American paleontologist Dale Guthrie received one of those calls that accelerate the pulse of any fossil lover like him. Some miners had found close to Fairbanks, in Alaska, which seemed to be part of the body of a bison of the ice age. At least that was what suggested the confusing knead of hooves, legs and skin that had peeked between the mud while the operators were looking for gold. Years after that call (and after intense work through) Guthrie and his colleagues celebrated the one who has probably been one of the most delusional banquets in the history of humanity: a stew with flesh of 55,000 years. What the hell is this? Something such that Walter Roman and his family have to think about the summer of 1979, when they discovered in a mine north of Fairbanks (Alaska) something that little or nothing had to do with the gold they were looking for. While working in the area they realized that something appeared between the frozen land: the remains of what seemed like a Ancient ancient creature of tens of thousands of years. They were so surprised that they warned of the finding and the news ended up arriving at Guthriepaleontologist at the University of Alaska Fairbanks (UAF). Something better than gold. Guthrie had to drive about an hour On gravel roads to get to the Roman mine, but the effort was worth it. Once there he observed what they looked like muscle tissues, bones and black hair, the remains of an ancient semi -soured steparia creature between the ice. “Roman’s finding was a novelty for both. He had found an authentic mummy, an exceptional event,” I would report Years later Guthrie in one of his books. The body had peeked thanks to the force of the hose with which the miners worked, powerful enough to remove part of the frozen mud, but not to completely release the body. Seeing him Guthrie decided to finish the task to prevent the meat from breaking down. With you, the Bison Priscus. The paleontologist concluded that what he had before him was a Bison Priscusan exceptionally well -preserved steparium bison if you take into account that tens of thousands of years had lived. Unfortunately, not everything was good news. Ice accumulations prevented removing the body quickly. And the summer heat played against him. To get out of trouble Guthrie took A decision Worthy of King Solomon: he waited for a large part of the body to appear, cut what could be preserved in one of the powerful freezers of the UAF and then excavated the rest of the body that was still embedded in the icy mud, which included the head and neck of the animal. When he had all the pieces he assembled them with the help of a specialized taxidermist. Not just that. As it details An article Published in 1986 in the Magazine of the University of Alaska (UA), the researchers were responsible for preserving the bones, hairs, insects, wood fragments and plants … any fragment that would be hidden among the ice, however insignificant, to rebuild the last instant of the life of the bison. For that same reason, the geology of the area analyzed in detail, in addition to the orientation and position in which the body was. Once the work was completed they baptized the animal ‘Blue Babe’. Why ‘Blue Babe’? For a double wink. The first, to the coloration that acquired the body for the chemical reactions that occurred during the excavation. The body was covered with a layer of Vivianita that, when exposed to the air, acquired a bluish hue. The second is a reference to American folklore: Blue Babe It is the name of the blue ox that accompanies Paul Bunyan, a popular US and Canada figure, a strong and large lumberjack. A bloody story. So far the funniest part. What Guthrie and his colleagues discovered (in the excavation His wife also participatedMary Lee) when examining the body was much less enjoyable. On the back they found brands of claws and teeth that led them to conclude that Blue Babe was killed by a Panthera Leoatrxan extinct and related feline with the African lions. The beast opened the side of the bison, killing and leaving exposed vertebrae, ribs and muscles that later were responsible for devouring other carnivores. A first radiocarbon dating of a skin fragment led them to think that this event occurred some 36,000 yearsalthough subsequent studies have proven that they fell short and traced it to 50,000 years. Much more than a fossil. He Panthera Leoatrx And the rest of the beasts who participated in the bloodthirsty Festin were not the only ones who put the vote at the coast of Blue Babe. When examining the body the scientists found out something else, that the bison died towards autumn or winter, which favored the body to cool quickly and ended up freezing before their 50,000 -year -old dream. Your state of conservation It was so extraordinarily good That the paleontologists found blood coagulated in the skin, bone marrow, fat … and something else: they found that the muscle tissue that the lion and rest of the beasts had not realized had a color and texture very similar to that of fresh meat. So, why treat it the same? “A small part of the neck”. “All of us who worked on this had heard the stories of the Russians who excavated things like bison and mammoths at the north end and were frozen enough to eat them,” He came to confess Guthrie in statements collected by Obscure atlas. “So we said: ‘Do you know what we can make’ prepare a meal with this bison ‘.” No sooner said than done. The paleontologist and his colleagues decided to try a piece of one of the best preserved parts of Blue Babe, the neck. The banquet was held in … Read more

Chinese researchers believe they have discovered a simple “trick” to lose weight: eat raw vegetables

For decades, scientists have discussed the effects of vegan and ovo -vegetarian diets on weight loss and heart disease prevention. Without much success, really. Not because The clues in favor have not accumulatedbut because something was missing. A common link, a thread that organized all that scientific evidence and gave meaning. In recent years, a team of doctors from the Qilu Hospital of the University of Shandong He thinks he found That piece that was missing. And it’s an important piece. Above all, because obesity is becoming The great epidemic of the 21st century. 1.9 billion overweight peoplesome 600 million people with obesity and up. Something that would not be a problem if it wasn’t because, like They wrote Yani Xu and his team in their research, “obesity and its associated complications not only lead to an increase in morbidity and mortality, but also to a reduction in quality of life.” Finding simple weight loss strategies goes beyond aesthetics or fashion: it is an investment in quality of life. But did not solve Ozempic? It is true that the arrival of Ozempic (and the rest of New agonist medications from LPG-1) has radically changed our way of seeing overweight: as Antonio Ortiz said, these medications are helping us understand that Metabolism and appetite are biological facts, not moral elections. Biological facts that, as we see, bring huge social consequences. Plan b. Therefore, although the “new ozempics” are being revolutionary, they are far from being the solution to all our problems. Not only is these very expensive medications (and obesity shows a clear correlation with greater rates of poverty and precariousness economic); They are not substitutes for healthier and more balanced habits. That’s where Yani Xu and his team enter. In search of lost evidence. Tracking in the previous bibliography, Chinese researchers found 24 studies that followed more than 2,000 people. They were quite quality studies (randomized clinical trials) and that has allowed them to conclude that there was a detail that showed very strong links with a lower risk of obesity and heart problems: raw vegetables. In fact, this is true even when they eliminated the effect of genetic factors from the equation. Something not too common and, therefore, very interesting. “The vegetarian diet is a viable option for people who wish to control their body weight and (prevent) metabolic diseases,” They explain. How is it possible? The researchers They shuffle some ideas: From its high content of phytosterols and fatty fats to its role in reducing inflammation and oxidative stress. However, it is not too clear: we have a statistical explanation, but we still lack a mechanism of action. We may have solved one of the big problems when establishing a clear relationship between weight loss and veganism, but not at all. However, with the data that Let’s have on the tableit seems that the idea of ​​progressively increasing the weight of vegetables (and raw vegetables) seems like a positive strategy. More positive than we thought.
