Mary-Ev writes to offer this page of scientific arcana from the New Scientist. There’s a veritable treasure trove of concepts explained, mysteries solved and enigmas unenigmized here. For example, there’s that peculiar phenomenon that one experiences after eating asparagus:
A number of different sulphurous compounds have been implicated, though one of the most thorough investigations indicates that the effect may be caused by a cocktail which includes methanethiol, dimethyl sulphide, dimethyl disulphide, bis(methylthio)methane, dimethyl sulphoxide and dimethyl sulphone.
Thank goodness that’s cleared up (I can hear my biochemist sister typing up an explanation already).
