The Organosulfur Chemistry of the Genus Allium – Implications for the Organic Chemistry of Sulfur
TL;DR: A Cook's tour of the organosulfur chemistry of the genus Allium, as represented, inter alia, by garlic (Allium sativum L.) and onion(Allium cepa L.). as discussed by the authors reported on the biosynthesis of the S-alk(en)yl-L-cysteine S-oxides (aroma and flavor precursors) in intact plants and on how upon cutting or crushing the plants these precursor are cleaved by allinase enzymes, giving sulfenic acids.

PDDG/PM3 and PDDG/MNDO: improved semiempirical methods.
TL;DR: Two new semiempirical methods employing a Pairwise Distance Directed Gaussian modification have been developed, and yield heats of formation for compounds containing C, H, N, and O atoms with significantly improved accuracy over the standard NDDO schemes.
