Scientists in Cambridge University suggest molecules, vital to the development of life, could have formed from a process known as graphitization. Once verified in the laboratory, it could allow us to try and recreate plausible ...

A cyanide is a chemical compound that contains the cyano group, -C≡N, which consists of a carbon atom triple-bonded to a nitrogen atom. Cyanides most commonly refer to salts of the anion CN−. Most cyanides are highly toxic.
In organic chemistry compounds containing a -C≡N group are known as nitriles and compounds that contain the -N≡C group are known as isocyanides. Organic nitriles and isocyanides are far less toxic because they do not release cyanide ions easily.
The dye Prussian blue had been first accidentally made, it is presumed around 1706, from substances containing iron and carbon and nitrogen, and the (then unknown) cyanide was formed during the manufacture of the dye. An iron-containing compound was found in Prussian blue and named "ferrocyanide", meaning "blue substance with iron", from Latin ferrum = "iron" and Greek kyanos = "(dark) blue". When ferrocyanide was analyzed, removing the iron from the compound and from its name left "cyanide".
