Perspectives on Pyrochlores, Defect Fluorites, and Related Compounds: Building Blocks for Chemical Diversity and Functionality

In this article we provide some perspectives on a range of pyrochlore and defect fluorite type compounds with nominal A2B2O7, A2BO5, ABC2O7, and other stoichiometries.Typically, the phase transformations and stability fields in these systems are mapped as a function of the ionic radii of the A and B-site cations, e.g., the A/B cation radius ratio (

Apparent RNA bridging between PRC2 and chromatin is an artifact of non-specific chromatin precipitation upon RNA degradation

Summary: Polycomb repressive complex 2 (PRC2) modifies chromatin to maintain repression of genes specific for other cell lineages.In vitro, RNA inhibits PRC2 activity, but the effect of RNA on PRC2 in cells is less clear, with studies concluding that RNA either antagonizes or promotes PRC2 chromatin association.The addition of RNase A Sweats to chr
