This month's winning image was submitted by Paul Andrews (University of Dundee (p.d.andrews@dundee.ac.uk)). It shows two telophase cells from a stable HeLa cell line expressing green fluorescent protein (GFP)-tagged human Aurora B.

Microtubules are shown in red, INCENP in blue, Aurora B–GFP in green and DNA in white. The image is a maximum-intensity projection of a deconvolved 3D data set acquired on a DeltaVision Restoration microscope (Applied Precision LLC). Bar, 5 μm.

We are pleased to acknowledge the help of our two external advisors, Ariel Ruiz i Altaba (Developmental Genetics Program, New York Medical Center) and Lelio Orci (Department of Morphology, University Medical Center, Geneva).
