Cover picture: Fluorescence anisotropy imaging of functional chromatin organization in live cells depict spatiotemporal heterogeneity in compaction and its active maintenance. Anisotropy images are acquired in wild-type (WT), ATP depleted (ATP dep), and Staurosporine (Stau) treated HeLa cells. Scale bar, 10 µm. See the article by Banerjee et al. on page 2297.
