Light Year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distance, astronomical distances and is equal to exactly , which is approximately 9.46 trillion km or 5.88 trillion mi. As defined by the International Astronomical Union (IAU), a light-year is the distance that Speed of light, light travels in vacuum in one Julian year (astronomy), Julian year (365.25 days). Despite its inclusion of the word "year", the term should not be misinterpreted as a unit of time. The ''light-year'' is most often used when expressing distances to stars and other distances on a Galaxy, galactic scale, especially in public understanding of science, non-specialist contexts and popular science publications. The unit most commonly used in professional astronomy is the parsec (symbol: pc, about 3.26 light-years). Definitions As defined by the International Astronomical Union (IAU), the light-year is the product of the Julian year (astronomy), Julian ...

The A
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun '' the ...

Klingon Language
The Klingon language (, ''Klingon scripts, '': , ) is the constructed language spoken by a fictional alien race called the Klingons in the ''Star Trek'' universe. Described in the 1985 book ''The Klingon Dictionary'' by Marc Okrand and deliberately designed to sound "alien", it has a number of Linguistic typology, typologically uncommon features. The language's basic sound, along with a few words, was devised by actor James Doohan ("Montgomery Scott, Scotty") and producer Jon Povill for ''Star Trek: The Motion Picture''. The film marked the first time the language had been heard. In all previous appearances, Klingons spoke in English, even to each other. Klingon was subsequently developed by Okrand into a full-fledged language. Klingon is sometimes referred to as ''Klingonese'' (most notably in the ''Star Trek: The Original Series'' episode "The Trouble with Tribbles", where it was actually pronounced by a Klingon character as "Klingonee" ), but among the Klingon-speaking comm ...

Cinefantastique
''Cinefantastique'' is an American horror, fantasy, and science fiction film magazine. History The magazine originally started as a mimeographed fanzine in 1967, then relaunched as a glossy, offset printed quarterly in 1970 by publisher/ editor Frederick S. Clarke. Intended as a serious critical/review journal of the genres, the magazine immediately set itself apart from competitors like '' Famous Monsters of Filmland'' and '' The Monster Times'' due to its slick paper stock and use of full color interior film stills. ''Cinefantastiques articles and reviews emphasized an intelligent, near-scholarly approach, a then-unusual slant for such a genre-specific magazine. Advertisements were few, consisting mostly of other titles and materials by the publisher. The magazine quickly came to be known for its lengthy, information-filled "retrospective" articles devoted to the full production details of such classic films as 1951's '' The Day the Earth Stood Still'', George Pal's '' ...

Genetic Viability
Genetic viability is the ability of the genes present to allow a cell, organism or population to survive and reproduce. The term is generally used to mean the chance or ability of a population to avoid the problems of inbreeding. Less commonly genetic viability can also be used in respect to a single cell or on an individual level. Inbreeding depletes heterozygosity of the genome, meaning there is a greater chance of identical alleles at a locus. When these alleles are non-beneficial, homozygosity could cause problems for genetic viability. These problems could include effects on the individual fitness (higher mortality, slower growth, more frequent developmental defects, reduced mating ability, lower fecundity, greater susceptibility to disease, lowered ability to withstand stress, reduced intra- and inter-specific competitive ability) or effects on the entire population fitness (depressed population growth rate, reduced regrowth ability, reduced ability to adapt to environmental ...

Biological Reproduction
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself. The evolution of sexual reproduction is a major puzzle for biologists. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce and organisms only pass on 50% of their genes.John Maynard Smith ''The Evolution of Sex'' 1978. Sexual reproduction typically requires the sexual interaction of two specialized reproductive cells, called gametes, which contain half the number of chromosomes of normal cells and are created by me ...

Cloning
Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis. In the field of biotechnology, cloning is the process of creating cloned organisms of Cell (biology), cells and of DNA fragments. The artificial cloning of organisms, sometimes known as reproductive cloning, is often accomplished via somatic-cell nuclear transfer (SCNT), a cloning method in which a viable embryo is created from a somatic cell and an egg cell. In 1996, Dolly (sheep), Dolly the sheep achieved notoriety for being the first mammal cloned from a somatic cell. Another example of artificial cloning is molecular cloning, a technique in molecular biology in which a single living cell is used to clone a large population of cells that contain identical DNA molecules. In bioethics, there are a vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Pool
The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Description A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection. Meanwhile, low genetic diversity (see inbreeding and population bottlenecks) can cause reduced biological fitness and an increased chance of extinction, although as explained by genetic drift new genetic variants, that may cause an increase in the fitness of organisms, are more likely to fix in the population if it is rather small. When all individuals in a population are identical with regard to a particular phenotypic trait, the population is said to be 'monomorphic'. When the individuals show several variants of a particular trait they are said to be polymorphic. History The Russian geneticist Alexander Sergeevich Serebrovsky first formulated the concept in the 1920s as ''genofond'' (gene fund), ...
