A SWI/SNF-family chromatin remodeling subcomplex from yeast is identified (RSC1) that is specialized to slide nucleosomes residing on DNA sequences that confer partial nucleosome unwrapping, with assistance from accessory factors.

Seemingly contradictory findings of single-molecule and in vivo experiments on a major mechanism of chromosome organization are reconciled by computationally investigating mechanisms of loop extrusion that are consistent with both.

Proximity and homology guided inter-chromosomal translocations drive karyotype evolution.

Unbiased ChIP-seq screens and genetic knockouts of large Kruppel associated box zinc finger protein (KRAB-ZFP) clusters reveal that evolutionarily young KRAB-ZFPs play a redundant role in retrotransposon restriction in mice.

A long noncoding RNA uses viral mimicry to achieve developmental gene silencing across a chromosome.

By sterically hindering tRNA binding and inhibiting translation elongation, mRNA stem-loops can modulate gene expression.

Sister chromatid cohesion is established during replication by two independent pathways operating in parallel, one converts chromosomal cohesin into cohesive structures while the other loads cohesin onto nascent DNAs.

The molecular determinants for neuronal subcellular RNA transport by FMRP are defined, with interactions between RNA G-quadruplexes and the RGG domain of FMRP being of critical importance.

Crosslink immunopreciptiation (iCLIP) studies reveal important mechanistic insights into how MARF1 post-transcriptionally regulates targeted mRNAs and uncover a novel mode by which EDC4 regulates mRNA metabolism.

Genetic and biochemical studies show that a conserved ribosome biogenesis complex also localizes to heterochromatin, where it triggers RNA degradation and promotes the spreading and epigenetic inheritance of histone methylation.
