Science-Fiction Plus was a U.S. science fiction magazine published by Hugo Gernsback for seven issues in 1953.
 In 1926 Gernsback had launched "Amazing Stories," the first science fiction magazine, but he had not been involved in the genre since 1936, when he sold "Wonder Stories".
 "Science-Fiction Plus" was initially in slick format, meaning that it was large-size and printed on glossy paper.
 Gernsback had always believed in the educational power of science fiction, and he continued to advocate his views in the new magazine's editorials.
 The managing editor, Sam Moskowitz, had been a reader of the early pulp magazines, and published many writers who had been popular before World War II, such as Raymond Gallun, Eando Binder, and Harry Bates.
 Combined with Gernsback's earnest editorials, the use of these early writers gave the magazine an anachronistic feel.
 Sales were initially good, but soon fell.
 For the last two issues Gernsback switched the magazine to cheaper pulp paper, but the magazine remained unprofitable.
 The final issue was dated December 1953.
The Day the Earth Stood Still (a.k.a. Farewell to the Master and Journey to the World) is a 1951 black-and-white American science fiction film from 20th Century Fox, produced by Julian Blaustein, directed by Robert Wise, that stars Michael Rennie, Patricia Neal, Billy Gray, Hugh Marlowe, and Sam Jaffe.
 The screenplay was written by Edmund H. North, based on the 1940 science fiction short story "Farewell to the Master" by Harry Bates.
 The score was composed by Bernard Herrmann.
Worlds Unknown was a science-fiction comic book published by Marvel Comics in the 1970s that adapted classic short stories of that genre, including works by Frederik Pohl, Harry Bates, and Theodore Sturgeon.
North of the Yukon is a 24-page funny animal comic book adventure story featuring Scrooge McDuck and his nephews, Donald Duck and Huey, Dewey, & Louie.
 It was written and drawn by Carl Barks.
 This was his last story involving Scrooge's adventures in Alaska.
 It was published in September 1965, and later reprinted in May 1993.
 Gemstone Publishing later reprinted the story again in 2005 for a Donald Duck/Uncle Scrooge graphic novel with another story inspired by this one called "Somewhere in Nowhere".
 The character of Barko was inspired by an actual sled dog named Balto, who participated in the 1925 serum run to Nome.
 Barks had read an article about Balto in an issue of "National Geographic", and was inspired to create this character.

The Day the Earth Stood Still is a 2008 American science fiction film, a loose adaptation of the 1951 film of the same name.
 The screenplay by David Scarpa is based on the 1940 classic science fiction short story "Farewell to the Master" by Harry Bates and on the 1951 screenplay adaptation by Edmund H. North.
"Farewell to the Master" is a science fiction short story by American writer Harry Bates.
 It was first published in the October 1940 issue of "Astounding Science Fiction".
 It provided the basis of the 1951 film "The Day the Earth Stood Still" and its 2008 remake.
 In 1973, the story was adapted by Marvel Comics for its "Worlds Unknown" series with Bates' blessing.
Gort is a fictional humanoid robot that appeared first in the 1951 20th Century Fox American science fiction film "The Day the Earth Stood Still" and later in its 2008 remake.
 His depiction varies between film adaptations, however, the original character was loosely based on the character Gnut, from "Farewell to the Master", a 1940 "Astounding Science Fiction" short story written by Harry Bates, used as the basis for Edmund H. North's screenplay.
 In that story, Gnut is a moving green statue that is apparently attendant upon Klaatu, but in the terminus of the story is identified as the eponymous "master" over Klaatu.
