Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.

A chromatin boundary factor that is only active during early embryo development has been discovered in Drosophila.

Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

Structure-function analysis of the super elongation complex formed when HIV replicates inside cells reveals that the HIV-1 Tat protein binds to a cleft between P-TEFb, an enzyme that is involved in normal transcription, and AFF4, a protein that is used to build the super elongation complex

A gene that codes for a transcription factor that is involved in lipid and carbohydrate metabolism also has a role in the regulation of circadian rhythms.

Research on humans and dogs reveals that the communities of microorganisms found on the skin, on the tongue and in the intestine are affected differently by age and cohabitation.

Genetic studies in mice identify the transcription factor MafB as a potent regulator of specific features of the synapses underlying hearing.

Cryo electron microscopy and structure-based mutagenesis reveal that the bacteriophage BPP-1 contains two of the three major recognized viral folds, one of which exhibits a new topology.
