Oldest Organisms
This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum lifespans. For a given species, such a designation may include: # The oldest known individual(s) that are currently alive, with verified ages. # Verified individual record holders, such as the longest-lived human, Jeanne Louise Calment, or the longest-lived domestic cat, Creme Puff. The definition of "longest-living" used in this article considers only the observed or estimated length of an individual organism's natural lifespan – that is, the duration of time between its birth or conception, or the earliest emergence of its identity as an individual organism, and its death – and does not consider other conceivable interpretations of "longest-living", such as the length of time between the earliest appearance of a species in the fossil record and the present (the historical "age" of the species as a whole), the time betwee ...

Cloning
Cloning is the process of producing individual organisms with identical or virtually identical DNA, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction. In the field of biotechnology, cloning is the process of creating cloned organisms (copies) of Cell (biology), cells and of DNA fragments (molecular cloning). Etymology Coined by Herbert J. Webber, the term clone derives from the Ancient Greek word (), ''twig'', which is the process whereby a new plant is created from a twig. In botany, the term ''lusus'' was used. In horticulture, the spelling ''clon'' was used until the early twentieth century; the final ''e'' came into use to indicate the vowel is a "long o" instead of a "short o". Since the term entered the popular lexicon in a more general context, the spelling ''clone'' has been used exclusively. Natural cloning Cloning is a natural form of reproduction that has allowed life forms to spread for hundreds of millio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amber
Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects."Amber" (2004). In Maxine N. Lurie and Marc Mappen (eds.) ''Encyclopedia of New Jersey'', Rutgers University Press, . Amber is used in jewelry and has been used as a healing agent in folk medicine. There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions. Amber occurring in coal seams is also called resinite, and the term ''ambrite'' is applied to that found specifically within New Zealand coal seams. Etymology The English word ''amber'' derives from Arabic (ultimately from Middle Persian ''ambar'') via Middle Latin ''ambar'' and Middle French ''ambre''. The word was adopted in Middle English in the 14th century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kibbutz Keturah
Ketura ( he, קְטוּרָה) is a kibbutz in southern Israel. Located north of Eilat in the Aravah Valley, it falls under the jurisdiction of Hevel Eilot Regional Council. In it had a population of . Name The name Ketura was taken from a nearby hill and wadi, and is also the name of the second wife of Abraham (). History Ketura was founded in November 1973 by a group of young American Jewish immigrants, most of them members of the Zionist youth movement Young Judaea. Difficulties in the early years frustrated many of the inhabitants of the kibbutz, which caused many of the founders to leave. At the same time, more Young Judaeans joined the community, along with a variety of other immigrants as well as Israel Boy and Girl Scouts Federation graduates. Ketura is in the Southern Arava - Hevel Eilot Regional Council. Today Ketura has about 165 members and several young families who are candidates to become members. During the year there are about 500 people living on Ketura, mem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judean Date Palm
The Judean date palm is a date palm (''Phoenix dactylifera'') grown in Judea. It is not clear whether there was ever a single distinct Judean cultivar, but dates grown in the region have had distinctive reputations for thousands of years, and the date palm was anciently regarded as a symbol of the region and its fertility. Cultivation of dates in the region almost disappeared after the fourteenth century AD from a combination of climate change and infrastructure decay but has been revived in modern times. In 2005, a team of scientists sprouted a preserved 2,000-year-old seed, the oldest seed germinated with human-assistance (with the claim in 2012 of a 32,000-year-old arctic flower involving fruit tissue rather than a seed). The palm, a male tree, was named Methuselah (not to be confused with a bristlecone pine tree of the same name). Following this success, six further preserved seeds were sprouted. History Fruit of the date palm was considered a staple food in the Judaean D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germination
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Some plants produce varying numbers of seeds that lack embryos; these are empty seeds which never germinate. Dormant seeds are viable seeds that do ...

Alazeya River
The Alazeya ( rus, Алазея, r=; sah, Алаһыай, translit=Alahıay) is a river in the northeastern part of Yakutia, Russia which flows into the Arctic between the basins of the larger Indigirka to the west and the Kolyma to the east. Mount Kisilyakh-Tas is a notable kigilyakh site on the right bank of the Alazeya River at . Geography The river is long. The area of its basin is . The Alazeya is formed at the confluence of the Nelkan and Kadylchan rivers in the slopes of the Alazeya Plateau. It crosses roughly northwards through the tundra meandering among the flat, marshy areas of the Kolyma Lowland, part of the greater East Siberian Lowland. Finally the Alazeya drains into the Kolyma Bay of the East Siberian Sea, close to Logashkino. The river freezes in late September through early October and stays icebound until late May through early June. There are more than 24,000 lakes in its basin.

Kolyma River
The Kolyma ( rus, Колыма, p=kəlɨˈma; sah, Халыма, translit=Khalyma) is a river in northeastern Siberia, whose basin covers parts of the Sakha Republic, Chukotka Autonomous Okrug, and Magadan Oblast of Russia. The Kolyma is frozen to depths of several metres for about 250 days each year, becoming free of ice only in early June, until October. Course The Kolyma begins at the confluence of the Kulu and the Ayan-Yuryakh, originating in the Khalkan Range and flows across the Upper Kolyma Highlands in its upper course. Leaving the mountainous areas it flows roughly northwards across the Kolyma Lowland, a vast plain dotted with thousands of lakes, part of the greater East Siberian Lowland. The river empties into the Kolyma Gulf of the East Siberian Sea, a division of the Arctic Ocean. The Kolyma is long. The area of its basin is . The average discharge at Kolymskoye is , with a high of reported in June 1985, and a low of in April 1979. Tributaries The m ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

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 war ...

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...
