Biochemical, molecular, and genetic analyses show that in Drosophila the epigenetic enzyme TET does not demethylate 6mA, which is scarce in the genome, but rather acts in a catalytic-independent manner.

The coexistence of ancestral and innovative functions is possible and fosters evolutionary innovation in events involving the acquisition of whole protein domains.
A novel single-molecule sequencing method reveals previously unappreciated heterogeneity in nucleosome positioning on individual chromatin fibers across the human genome.
The establishment of Ustilago bromivora and Brachypodium as a biotrophic model system provides the foundation for studying new aspects of plant-pathogen interactions and for answering questions about fungal sex and speciation.

Fully assembled DNA methylomes from phylogeographically diverse clinical Mycobacterium tuberculosis complex isolates reveals 'intercellular mosaic methylation' as a source of epigenetic diversity.
A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.
