news (n.): late 14c., "new things," plural of new (n.) "new thing," from new (adj.); after French nouvelles, used in Bible translations to render Medieval Latin nova (neuter plural) "news," literally "new things."

Bad news "unpleasant person or situation" is from 1926. Expression no news, good news can be traced to 1640s. Expression news to me is from 1889.

The News in the Virginia city Newport News is said to derive from the name of one of its founders, William Newce.
rebus (n.): c. 1600, from Latin rebus "by means of objects," ablative plural of res "thing, object." According to French sources, principally from the phrase de rebus quæ geruntur "of things which are going on," in reference to the satirical pieces composed by Picardy clerks at carnivals, subtle satires of current events using pictures to suggest words, phrases or things. Or it may be from the representations being non verbis sed rebus "not by words, but by things." In either case from Latin res "thing."
revue (n.): 1872, "show presenting a review of current events," from French revue, from Middle French, literally "survey," noun use of fem. past participle of revoir "to see again" (see review (n.)). Later extended to shows consisting of a series of unrelated scenes.
swim (n.): 1540s, "the clear part of any liquid" (above the sediment), from swim (v.). Meaning "part of a river or stream frequented by fish" (and hence fishermen) is from 1828, and is probably the source of the figurative meaning "the current of the latest affairs or events" (as in in the swim "on the inside, involved with current events," 1869). Meaning "act of swimming" is from 1764.
