schwit1 quotes a report from ScienceAlert: Researchers have noted the first signs of obesity in the native ethnic groups of the Yamalo-Nenets region -- an autonomous district that sits on the coast of the Arctic Ocean in Northwest Siberia. According to local experts, obesity has not previously existed in these indigenous populations, but the first cases are now being reported, and a marked change in diet -- including instant noodles and pasta -- appears to be responsible. The Yamalo-Nenets Autonomous Okrug has a population of just over 522,000 people, whose ancestors have survived the permafrost for millennia. The nomadic Nenets and Khanty peoples have been herding reindeer up and down the Yamal tundra -- a 700-km-long peninsula that stretches deep into the Arctic Ocean -- for 1,000 years, with diets heavily based on venison and fish. But that appears to be changing fast, as researchers note the increasing uptake of chemically processed foods, such as instant noodles and pasta, and the addition of sugar, pastry, and bread to their diets. According to Titovsky, these changes -- which have only been occurring over the past few years -- have seen the intake of venison and river fish cut by half.

An anonymous reader writes There's great news coming out of Russia for epic road trip lovers. Russian Railways president Vladimir Yakunin has proposed building a highway that would reach from London to Alaska via Russia, a 13,000-mile stretch of road. "This is an inter-state, inter-civilization, project," the Siberian Times quoted Yakunin. "The project should be turned into a world 'future zone,' and it must be based on leading, not catching, technologies."

New submitter Sardaukar86 sends this excerpt from a Washington Post report: In the middle of last summer came news of a bizarre occurrence no one could explain. Seemingly out of nowhere, a massive crater appeared in one of the planet's most inhospitable lands. Early estimates said the crater, nestled in a land called "the ends of the Earth" where temperatures can sink far below zero, yawned nearly 100 feet in diameter. The saga deepened. The Siberian crater wasn't alone. There were two more, ratcheting up the tension in a drama that hit its climax as a probable explanation surfaced. Global warming had thawed the permafrost, which had caused methane trapped inside the icy ground to explode.

Now, however, researchers fear there are more craters than anyone knew — and the repercussions could be huge. Russian scientists have now spotted a total of seven craters, five of which are in the Yamal Peninsula. Two of those holes have since turned into lakes. And one giant crater is rimmed by a ring of at least 20 mini-craters, the Siberian Times reported.

New submitter DavidMZ writes: The Siberian Times reports on a large crater of unknown origin that has appeared in the Yamal Peninsula in northern Siberia. The Russian government has dispatched a group of scientists to investigate the 80-meter-wide crater. Anna Kurchatova from Siberia's Sub-Arctic Scientific Research Center believes the crater was a result of an explosion when a mixture of water, salt, and natural gas exploded underground. The Yamai Peninsula is known to hold Russia's biggest natural gas reserve."

EwanPalmer sends a followup to a story from last year about a team of Siberian scientists who recovered an ancient wooly mammoth carcass. It was originally believed to be about 10,000 years old, but subsequent tests showed the animal died over 43,000 years ago. The scientists have been surprised by how well preserved the soft tissues were. They say it's in better shape than a human body buried for six months. "The tissue cut clearly shows blood vessels with strong walls. Inside the vessels there is haemolysed blood, where for the first time we have found erythrocytes. Muscle and adipose tissues are well preserved." The mammoth's intestines contain vegetation from its last meal, and they have the liver as well. The scientists are optimistic that they'll be able to find high quality DNA from the mammoth, and perhaps even living cells. They now say there's a "high chance" that data would allow them to clone the mammoth.

westtxfun writes "'Russian scientists claimed Wednesday they have discovered blood in the carcass of a woolly mammoth, adding that the rare find could boost their chances of cloning the prehistoric animal.' As scientists unearthed the recent find, very dark blood flowed out from beneath the mammoth, and the muscle tissue was red. This is the best-preserved specimen found so far and they are hopeful they can recover DNA and clone a mammoth. Semyon Grigoriev, one of the researchers, said, 'The approximate age of this animal is about 10,000 years old. It has been preserved thanks to the special conditions, due to the fact that it did not defrost and then freeze again. We suppose that the mammoth fell into water or got bogged down in a swamp, could not free herself and died. Due to this fact the lower part of the body, including the lower jaw, and tongue tissue, was preserved very well. The upper torso and two legs, which were in the soil, were gnawed by prehistoric and modern predators and almost did not survive.'"
