Alien (law)
In law, an alien is a person who resides within the borders of a country and is not a national of that country, though definitions and terminology differs to some degree.
Etymology
The term "alien" is derived from the Latin alienus, meaning stranger, foreign.
Categories
Different countries use varying terms for "aliens" including:
- a nonresident alien is a non-citizen who is visiting a country, for example as a tourist, on business, entertainers, sportspeople or in the country to receive medical treatment.
- a resident alien is a non-citizen who has temporary resident status in a country.
Alien (creature in Alien franchise)
The "Alien" (also referred to as a "Xenomorph") is a fictional endoparasitoid extraterrestrial arthropodal species that is the eponymous antagonist of the Alien film series. The species made its debut in the film Alien (1979), and reappeared in the sequels Aliens (1986), Alien 3 (1992), and Alien: Resurrection (1997), as well as the crossover franchise Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007). A similar creature of a slightly different design also briefly appears in the Ridley Scott film Prometheus (2012). In addition, the Alien appears in various literature and video game spin-offs from the franchises.
Unlike many other extraterrestrial races in science fiction, the Aliens lack a technological civilization and are predatory creatures with no higher goals than the propagation of their species and the ultimate destruction of lifeforms that could pose a threat to them. Like wasps or termites, Aliens are eusocial, with a single fertile queen breeding a caste of warriors. The Aliens' biological life cycle involves traumatic implantation of endoparasitoid larvae inside living hosts; these larvae erupt from the host's chest or intestines after a short incubation period, rapidly mature from juvenile into adulthood, and seek out more hosts for implantation.
Alien (franchise)
Alien is a science-fiction horror film franchise centered on a film series that depicts Warrant Officer Ellen Ripley (Sigourney Weaver) and her battles with an extraterrestrial lifeform, commonly referred to as "the Alien".
Produced by 20th Century Fox, the series began with Alien (1979), directed by Ridley Scott. It was followed by three sequels, released in 1986, 1992 and 1997. A planned prequel series directed by Scott is in development, beginning with the 2012 release of Prometheus.
The series has led to numerous books, comics and video game spin-offs. Related to the franchise is the two-part Alien vs. Predator series, which combines the continuities of Aliens with the Predators from the Predator film series.
Background
After completion of the film Dark Star (1974), writer Dan O'Bannon thought to develop some of the ideas (especially the theme of "alien hunts crew through a spaceship") and create a science-fiction horror film. Provisionally called Memory, screenwriter Ronald Shusett collaborated with O'Bannon on the project, adding elements from a previous O'Bannon script, Gremlins, which featured gremlins causing mayhem aboard a World War II bomber and wreaking havoc with the crew. The duo finished the script, initially entitled Star Beast, which was later changed to Alien after O'Bannon noticed the number of times the word "alien" occurred in the script. Their script was sold to Brandywine Productions, a company formed by producers Gordon Carroll, David Giler, and Walter Hill that had a distribution deal with 20th Century Fox. The writers imagined a low-budget film, but the success of Star Wars inclined 20th Century Fox to invest millions on the production.
Genetically modified organism
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques (i.e. genetically engineered organism). GMOs are the source of medicines and genetically modified foods and are also widely used in scientific research and to produce other goods.The term GMO is very close to the technical legal term, 'living modified organism', defined in the Cartagena Protocol on Biosafety, which regulates international trade in living GMOs (specifically, "any living organism that possesses a novel combination of genetic material obtained through the use of modern biotechnology").
A more specifically defined type of GMO is a "Transgenic Organism". This is an organism whose genetic makeup has been altered by the addition of genetic material from another, unrelated organism. This should not be confused with the more general way in which "GMO" is used to classify genetically altered organisms, as typically GMOs are organisms whose genetic makeup has been altered without the addition of genetic material from an unrelated organism.
