In the January 4th edition of biobytes, Shawn Jordan and Julie Canman

(Columbia University, New York, NY) describe how PAR Polarity proteins promote

robust cytokinesis during asymmetric cell division (Jordan et

al.), and Andrei Mardaryev (University of Bradford, Bradford, England, UK)

explains how the Polycomb protein Cbx4 regulates epidermal development (Mardaryev et

al.). Plus a round-up of other highlights from The Journal of

Cell Biology. The show was written and produced by Caitlin Sedwick and

Ben Short. Presented by Ben Short. See the associated papers in

JCB for details on the funding provided to support these

original research studies.
