    Intrinsically disordered linkers determine the interplay between phase separation and gelation in multivalent proteins

    Tyler S Harmon et al.
    Computational modeling and theoretical analysis reveal how disordered linkers determine whether linear multivalent proteins undergo gelation with or without phase separation.

    Kin cell lysis is a danger signal that activates antibacterial pathways of Pseudomonas aeruginosa

    Michele LeRoux et al.
    The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.

    The zinc finger proteins ZNF644 and WIZ regulate the G9a/GLP complex for gene repression

    Chunjing Bian et al.
    Repression of gene expression by the histone methyltransferase G9a is guided by two zinc finger proteins that can recognize consensus sequences in DNA.

    Phloem unloading in Arabidopsis roots is convective and regulated by the phloem-pole pericycle

    Timothy J Ross-Elliott et al.
    A study of solute and macromolecule trafficking in plants reveals a previously undescribed route for carbon distribution in growing root tissues.

    Multi-step coordination of telomerase recruitment in fission yeast through two coupled telomere-telomerase interfaces

    Xichan Hu et al.
    A telomerase recruitment mechanism delivers cell cycle information to the telomere-telomerase interface to ensure timely telomerase engagement at the telomere.

    Cell-cycle dependent phosphorylation of yeast pericentrin regulates γ-TuSC-mediated microtubule nucleation

    Tien-chen Lin et al.
    Phosphorylation of Spc110 N-terminal domain encompassing conserved motifs and its interaction with conserved GCP3 N-terminal domain regulate the oligomerization of gamma-tubulin small complexes (γ-TuSCs).

    High-molecular-weight polymers from dietary fiber drive aggregation of particulates in the murine small intestine

    Asher Preska Steinberg et al.
    Polymers from dietary fiber can control the aggregation of particulates in the murine small intestine in a manner qualitatively consistent with depletion interactions.

    A case study for a psychographic-behavioral segmentation approach for targeted demand generation in voluntary medical male circumcision

    Sema K Sgaier et al.
    A novel, hybrid segmentation technique reveals human heterogeneity in barriers towards a behavior, and is applied to characterize distinct segments in voluntary medical male circumcision.
