    A lipid bound actin meshwork organizes liquid phase separation in model membranes

    Alf Honigmann et al.
    A combination of imaging experiments and computer simulations on a model lipid membrane integrate the 'picket fence' and 'raft' models, and suggest that the interplay between actin binding, lipid phase separation and curvature compartmentalize the membrane.

    Oscillatory phase separation in giant lipid vesicles induced by transmembrane osmotic differentials

    Kamila Oglęcka et al.
    Spontaneous osmoregulation in giant phospholipid vesicles, which is characterized by oscillations in vesicle size and membrane tension, couples to the compositional degrees of freedom at the membrane surface to produce oscillations in domain texture and induce isothermal phase change.

    Narrow equilibrium window for complex coacervation of tau and RNA under cellular conditions

    Yanxian Lin et al.
    Liquid-liquid phase separation of tau is demonstrated to be an equilibrium state, stable only within a narrow range near physiological conditions, and thus has the capacity to regulate biological processes.

    Protein sorting by lipid phase-like domains supports emergent signaling function in B lymphocyte plasma membranes

    Matthew B Stone et al.
    Clustering the B cell receptor generates a membrane domain analogous to the liquid-ordered phase, localizing proteins involved in early receptor activation.

    Distinct stages in stress granule assembly and disassembly

    Joshua R Wheeler et al.
    A new stress granule assembly mechanism has implications for other RNP granules and pathological aggregates.

    CPEB4 is regulated during cell cycle by ERK2/Cdk1-mediated phosphorylation and its assembly into liquid-like droplets

    Jordina Guillén-Boixet et al.
    CPEB4's switch from translational repressor to activator is regulated during cell cycle by hyperphosphorylation of its intrinsically disordered domain, which controls its phase-separation into RNA-containing liquid-like droplets.

    Pat1 promotes processing body assembly by enhancing the phase separation of the DEAD-box ATPase Dhh1 and RNA

    Ruchika Sachdev et al.
    The protein Pat1 functions in the assembly of processing bodies, cellular membraneless organelles, by promoting the liquid–liquid phase separation of the DEAD-box ATPase Dhh1 and RNA.

    Point of View: Tuberculosis innovations mean little if they cannot save lives

    Madhukar Pai, Jennifer Furin
    Ending the TB epidemic requires scaling up access to new TB tools so that they can benefit the patients in low- and middle-income countries that need them the most.
