Yuka (mammoth)
Yuka is the best-preserved woolly mammoth (''Mammuthus primigenius'') carcass ever found. It was discovered by local Siberian tusk hunters in August 2010. They turned it over to local scientists, who made an initial assessment of the carcass in 2012. It is displayed in Moscow. Discovery The mammoth was found along the Oyogos Yar coast of the Dmitry Laptev Strait, approximately west of the mouth of the Kondratievo River, Siberia (72° 40′ 49.44″ N, 142° 50′ 38.35″) in the region of the Laptev Sea. Yuka is a juvenile female natural mummy that was found near and named after the village of Yukagir, whose local people discovered it. This mammoth mummy was found as an overhanging ledge about above the beach level in a low wave-cut bluff that was about high. The north-facing bluff was composed of loess that forms part of a rich Late Pleistocene fossil-bearing yedoma exposed by coastal erosion. The yedoma consists of ice-rich silts and silty sand penetrated by large ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woolly Mammoth
The woolly mammoth (''Mammuthus primigenius'') is an extinct species of mammoth that lived during the Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with '' Mammuthus subplanifrons'' in the early Pliocene. The woolly mammoth began to diverge from the steppe mammoth about 800,000 years ago in East Asia. Its closest extant relative is the Asian elephant. DNA studies show that the Columbian mammoth was a hybrid between woolly mammoths and another lineage descended from steppe mammoths. The appearance and behaviour of this species are among the best studied of any prehistoric animal because of the discovery of frozen carcasses in Siberia and North America, as well as skeletons, teeth, stomach contents, dung, and depiction from life in prehistoric cave paintings. Mammoth remains had long been known in Asia before they became known to Europeans in the 17th century. The origin of these remains was long a matt ...

Coastal Erosion
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels, bridges, columns, and pillars. Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away. Also erosion co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vice (magazine)
''Vice'' (stylized in all caps) is a Canadian-American magazine focused on lifestyle, arts, culture, and news/politics. Founded in 1994 in Montreal as an alternative punk magazine, the founders later launched the youth media company Vice Media, which consists of divisions including the printed magazine as well as a website, broadcast news unit, a film production company, a record label, and a publishing imprint. As of February 2015, the magazine's editor-in-chief is Ellis Jones. History Founded by Suroosh Alvi, Gavin McInnes, and Shane Smith (the latter two being childhood friends), the magazine was launched in 1994 as the ''Voice of Montreal'' with government funding. The intention of the founders was to provide work and a community service. When the editors later sought to dissolve their commitments with the original publisher, Alix Laurent, they bought him out and changed the name to ''Vice'' in 1996. Richard Szalwinski, a Canadian software millionaire, acquired the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kindai University
is a private non-sectarian and coeducational university based in Higashiosaka, Osaka, Japan with campuses in five other locations: Nara, Nara; Ōsakasayama, Osaka; Uchita, Wakayama; Higashihiroshima, Hiroshima; and Iizuka, Fukuoka. The English name of the university had been ''Kinki University'' since its establishment in 1949 to refer to "the surrounding area of the capital city (Kyoto)". On May 20, 2014, the university announced that its English name would officially change to , to avoid the implications of the word "kinky", as the university was planning to globalize with the establishment of a new Foreign Language school. The name change took effect on April 1, 2016. History The university dates its foundation to the establishment of in 1925. Kindai University started in 1949 when the founder college merged with , established in 1943. The first president was Koichi Seko.

Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global ...

Weichselian
The Weichselian glaciation was the last glacial period and its associated glaciation in northern parts of Europe. In the Alpine region it corresponds to the Würm glaciation. It was characterized by a large ice sheet (the Fenno-Scandian ice sheet) that spread out from the Scandinavian Mountains and extended as far as the east coast of Schleswig-Holstein, northern Poland and Northwest Russia. This glaciation is also known as the Weichselian ice age (german: Weichsel-Eiszeit), Vistulian glaciation, Weichsel or, less commonly, the Weichsel glaciation, Weichselian cold period (''Weichsel-Kaltzeit''), Weichselian glacial (''Weichsel-Glazial''), ''Weichselian Stage'' or, rarely, the Weichselian complex (''Weichsel-Komplex''). In Northern Europe it was the youngest of the glacials of the Pleistocene ice age. The preceding warm period in this region was the Eemian interglacial. The last cold period began about 115,000 years ago and ended 11,700 years ago. Its end corresponds with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Isotope Stage
Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS), are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep sea core samples. Working backwards from the present, which is MIS 1 in the scale, stages with even numbers have high levels of oxygen-18 and represent cold glacial periods, while the odd-numbered stages are lows in the oxygen-18 figures, representing warm interglacial intervals. The data are derived from pollen and foraminifera (plankton) remains in drilled marine sediment cores, sapropels, and other data that reflect historic climate; these are called proxies. The MIS timescale was developed from the pioneering work of Cesare Emiliani in the 1950s, and is now widely used in archaeology and other fields to express dating in the Quaternary period (the last 2.6 million years), as well as providing the fullest and best data for ...

Radiocarbon
Carbon-14, C-14, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California. Its existence had been suggested by Franz Kurie in 1934. There are three naturally occurring isotopes of carbon on Earth: carbon-12 (), which makes up 99% of all carbon on Earth; carbon-13 (), which makes up 1%; and carbon-14 (), which occurs in trace amounts, making up about 1 or 1.5 atoms per 1012 atoms of carbon in the atmosphere. Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 () through beta decay. A g ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to ...

Syngenetic Permafrost Growth
Syngenetic permafrost growth is a mode of the growth of permafrost whereby additional material is deposited to a permafrost site during freezing conditions, causing the permafrost layer to build upwards. It is cited as an efficient mode of permafrost growth, compared with heterogenetic permafrost growth, which occurs when freezing temperatures penetrate into previously unfrozen ground of uniform composition. Lunardini gives the basic formulas for permafrost generation under both modes. Syngenetic deposition of frozen materials comes from any of a variety of sources, sediment from streams and rivers, material fallen from hillsides, material blown by the wind, and material deposited at the bottom of lakes. Studies of such formations are partly based on observations in the Cold Regions Research and Engineering Laboratory tunnel into permafrost near Fairbanks, Alaska Fairbanks is a home rule city and the borough seat of the Fairbanks North Star Borough in the U.S. state of A ...
