    Multiple sources of slow activity fluctuations in a bacterial chemosensory network

    Remy Colin et al.
    Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.

    Repeated outbreaks drive the evolution of bacteriophage communication

    Hilje M Doekes et al.
    Mathematical modelling suggests that the evolution of communication between bacterial viruses requires repeated outbreak events, and the model then predicts typical communication strategies.

    Spatial control of irreversible protein aggregation

    Christoph Weber et al.
    A theoretical basis for the spatial regulation of protein aggregation shows how aggregates can partition preferentially into intracellular liquid compartments.

    Can Hamilton’s rule be violated?

    Matthijs van Veelen
    Hamilton's rule can be violated when costs and benefits of cooperation are defined using the counterfactual method, and when they depend on the cooperation of others.

    Cooperative base pair melting by helicase and polymerase positioned one nucleotide from each other

    Divya Nandakumar et al.
    A detailed model of the T7 replisome with the precise positions of the helicase and polymerase at the replication fork explains how catalysis by the two enzymes is coordinated.

    Quantitative dissection of transcription in development yields evidence for transcription-factor-driven chromatin accessibility

    Elizabeth Eck et al.
    Confronting different models of chromatin accessibility with temporally resolved transcription profiles favors a scenario where transcription factors actively, rather than passively, drive chromatin from the inaccessible to the accessible state.

    Quantitative regulation of the dynamic steady state of actin networks

    Angelika Manhart et al.
    Cells are able to control the actin network length and steering by adjusting geometric, structural, or biochemical parameters such as ADF/Cofilin and actin concentrations, and network width.

    Negative reciprocity, not ordered assembly, underlies the interaction of Sox2 and Oct4 on DNA

    John W Biddle et al.
    Rigorous reanalysis of single-molecule data yields evidence for energy expenditure in the interaction of transcription factors on DNA.

    Kinetic mechanism of coupled binding in sodium-aspartate symporter GltPh

    SeCheol Oh, Olga Boudker
    Sodium ions control the rates of both substrate binding and dissociation of an archaeal homologue of glutamate transporters in a manner that minimizes binding intermediates and maximizes transport efficiency.

    Regulation of the PI3K pathway through a p85α monomer–homodimer equilibrium

    Lydia WT Cheung et al.
    The p85α homodimer plays a role in the PI3K pathway by regulating PTEN function.
