    The activity-dependent histone variant H2BE modulates the life span of olfactory neurons

    Stephen W Santoro, Catherine Dulac
    A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

    Population structuring of multi-copy, antigen-encoding genes in Plasmodium falciparum

    Yael Artzy-Randrup et al.
    Mathematical modeling shows that local populations of the malaria parasite self-organize into a limited number of transient but distinct strains through competition for hosts in immunity space.

    SEC24A deficiency lowers plasma cholesterol through reduced PCSK9 secretion

    Xiao-Wei Chen et al.
    COPII vesicles regulate the metabolism of cholesterol through the selective transport of secretory proteins.

    The rise and fall of the Phytophthora infestans lineage that triggered the Irish potato famine

    Kentaro Yoshida et al.
    The strain of Phytophthora infestans that caused the Great Famine in the late 1840s was caused by a single genotype that is distinct from, but closely related to, the most prevalent modern genotype.

    Temporal transcriptional response to ethylene gas drives growth hormone cross-regulation in Arabidopsis

    Katherine Noelani Chang et al.
    The plant hormone ethylene regulates the expression of multiple genes in the model plant Arabidopsis, including those that respond to other hormones.

    Direct live imaging of cell–cell protein transfer by transient outer membrane fusion in Myxococcus xanthus

    Adrien Ducret et al.
    Physical contact between two Myxococcus xanthus cells is sufficient to fuse their outer membrane transiently and exchange outer membrane proteins and lipids at high efficiency.

    Minor introns are embedded molecular switches regulated by highly unstable U6atac snRNA

    Ihab Younis et al.
    Hundreds of cell growth and stress response genes are controlled by a rare small RNA component of an ancient splicing machinery, providing a raison d'être for its previously unexplained evolutionary conservation.

    DNA methylation presents distinct binding sites for human transcription factors

    Shaohui Hu et al.
    A comprehensive study of human transcription factors reveals that a greater number of these proteins bind to methylated DNA sequences than previously thought.
