Via MetaFilter, Cabinet Magazine Online. Cabinet is an award-winning quarterly magazine of art and culture whose name alludes to the the 17th-century "cabinet of curiosities" (aka Wunderkammer), a form of mini-museum of interesting objects, more often than not a little morbid, typically drawn eclectically from a variety of genres: art, general science, biology, archaeology, palaeontology, and so on.
So far, Cabinet is up to issue 29, each issue built around a theme (for instance, Failure, The Sea, Ruins, and Mountains) and a good proportion are online. A few articles I liked on an initial exploration: A Minor History of / Giant Spheres; Dead Troops Salute (Arthur Mole's symbolic photographics made from massed military formations); Leftovers / The London Necropolis Railway (the little-known railway that served Brookwood Cemetery - more here); The Scale and the Spectrum (a history of colour-music systems; Extraordinary voyages (about the adventurers who went over Niagara Falls in a barrel); Hashima: The Ghost Island; and so on). Dip and enjoy.
