Phonetics attempts to describe and understand how speech is produced and perceived; phonology attempts to understand the patterning—in general, the behavior—of speech sounds in particular languages and in all languages. Is phonetics part of phonology? This straightforward question has received various answers at different points in the history of linguistics. In this paper I attempt to document...

T development of a systematic design process for synthetic gene regulatory networks is an intriguing prospect that could improve both our understanding of regulatory motifs and our techniques for constructing novel applications. Such a design process would entail analysis tools capable of reliably predicting the in vivo behavior resulting from a given regulatory architecture. As with the proces...

M ultivesicular bodies (MVBs) are specialized endosomes that promote the degradation of membrane proteins by delivering them to lysosomes. This process is regulated by a series of endosomal sorting complexes required for transport (ESCRTs) (1). The ESCRT-0,-I, and-II complexes sequester ubiquitinated membrane proteins and recruit the ESCRT-III complex to drive the invagination and release of ca...
