Finding genes involved in complex behavioral outcomes, and understanding the pathways by which they confer risk, is a challenging task, necessitating large samples that are phenotypically well characterized across time. We describe an effort to create a university-wide research...

Strain-promoted oxidative annulation of arynes and cyclooctynes with benzamides: palladium-catalyzed C-H/N-H activation for the synthesis of N-heterocycles.

Organic letters

Front Microbiol. 2014 Jul 23;5:369. doi: 10.3389/fmicb.2014.00369. eCollection 2014.

With only hundreds of genes contained within their genomes, mycoplasmas have become model organisms for precise understanding of cellular processes, as well as platform organisms for predictable engineering of microbial functions for mission-critical applications. Despite the availability of "whole...
