    The cooperative binding of TDP-43 to GU-rich RNA repeats antagonizes TDP-43 aggregation

    Juan Carlos Rengifo-Gonzalez et al.
    The RNA-mediated higher order assembly of TDP-43, a protein associated with neurodegenerative diseases, preserves its solubility by reducing the risk of multivalent interactions between low complexity domains.

    HspB8 prevents aberrant phase transitions of FUS by chaperoning its folded RNA-binding domain

    Edgar E Boczek et al.
    Quantitative time-resolved crosslinking mass spectrometry is developed to monitor protein interactions and dynamics inside molecular condensates and used to identify misfolding of the RNA-binding domain of FUS as a key driver of condensate-aging.

    Binocular rivalry reveals an out-of-equilibrium neural dynamics suited for decision-making

    Robin Cao et al.
    The statistics of binocular rivalry at different combinations of image contrast is reproduced quantitatively by competing out-of-equilibrium populations of independent neural assemblies with idealized attractor dynamics.

    The solubility product extends the buffering concept to heterotypic biomolecular condensates

    Aniruddha Chattaraj et al.
    The solubility product, a thermodynamic concept classically applied to poorly soluble ionic solutes, can rationalize the concentration dependence for liquid-liquid phase separation of multicomponent multivalent molecules.

    Phenotypic plasticity underlies local invasion and distant metastasis in colon cancer

    Andrea Sacchetti et al.
    Colon cancer cells disseminate and colonize distant organ sites along the invasion-metastasis cascade by transiently activating intermediate epithelial to mesenchymal transition states through distinct transcriptional trajectories.

    Serine phosphorylation regulates the P-type potassium pump KdpFABC

    Marie E Sweet et al.
    Phosphorylation of a highly conserved serine residue is a physiological response of Escerichia coli to environmental potassium levels that inhibits transport by KdpFABC to maintain cellular homeostasis.

    Dynamic metastable long-living droplets formed by sticker-spacer proteins

    Srivastav Ranganathan, Eugene I Shakhnovich
    Multi-scale simulations reveal a potential, ATP-independent mechanism resulting in the formation of the long-living multi-droplet state by multi-valent, spacer-sticker proteins.

    Centering and symmetry breaking in confined contracting actomyosin networks

    Niv Ierushalmi et al.
    Novel mechanisms for cellular centering and symmetry breaking involving persistent contractile actomyosin flows and their hydrodynamic interactions with the fluid cytosol are presented and studied using a minimal, reconstituted system.

    A first order phase transition mechanism underlies protein aggregation in mammalian cells

    Arjun Narayanan et al.
    Quantitative single molecule and super resolution imaging in mammalian cells reveal a population of precursor aggregates describable by first order phase transition theory.
