De novo formation of centromeres creates diverse karyotypes in flies and is accompanied by rapid turnover of centromere-associated satellite repeats.

A stable tetrameric nucleosome occupies the central segment of each ∼120-bp budding yeast centromere in two rotational phases of both reflectional orientations in vivo.

The chromosomal passenger complex interacts with the inner kinetochore COMA complex through the Ctf19 C-terminus in vitro which is shown to be important for mediating accurate chromosome segregation.

Common ancestries, activities and structural determinants of a modular (bi-)polarization control system encoded in free-living and obligate intracellular α-proteobacteria, including the rickettsial pathogens, are described.

Measuring and simulating chromatin dynamics reveals that repositioning of genes to the nuclear pore is neither active nor vectorial, but reduces sub-diffusion and coordinates movement between loci on different chromosomes.

The meiotic DNA recombination landscape is locally influenced by the kinetochore to minimize potentially deleterious pericentromeric crossover recombination.

High-resolution mapping of cohesin-dependent chromatin loops in the genome of budding yeast reveals evolutionarily conserved features for loop formation and cohesin residency as a determinant of loop positioning.

Meiotic recombination and chromosome segregation require the establishment of chromatin boundaries by the acetyltransferase Eco1, which anchors both chromatin loops and cohesion.

Telomeric proteins Taz1 or Mit1 specifically regulate telomere association of condensin which is essential for sister-telomere disjunction in mitosis by restraining telomere association of cohesin.

Directly exerting force on the mammalian spindle reveals local and short-lived reinforcement in the spindle center, well-suited to preserve connections to chromosomes over seconds and yet allow remodeling over minutes.
