James Rego gives a talk at LC2CAM conference about reactions of chiral pyruvate esters and light to produce to chiral agents, reactivity of these molecules, and directions for best results.

Integrating the forces that fold tissues

submitted by: JCB
During gastrulation, pulsed contractions of the actomyosin cytoskeleton apically constrict a strip of cells on the ventral surface of Drosophila embryos. Martin et al. examine how these contractile forces are integrated across the tissue so that it invaginates to form the embryonic mesoderm. This biosights episode presents the paper by Martin et al. from the March 8, 2010 issue of The Journal of Cell Biology, and includes an interview with lead author Adam Martin.
