  text: In the presence of an obstacle, active particles condensate into a surface
    “wetting” layer due to persistent motion. If the obstacle is asymmetric, a rectification
    current arises in addition to wetting. Asymmetric geometries are therefore commonly
    used to concentrate microorganisms like bacteria and sperms. However, most studies
    neglect the fact that biological active matter is diverse, composed of individuals
    with distinct self-propulsions. Using simulations, we study a mixture of “fast”
    and “slow” active Brownian disks in two dimensions interacting with large half-disk
    obstacles. With this prototypical obstacle geometry, we analyze how the stationary
    collective behavior depends on the degree of self-propulsion “diversity,” defined
    as proportional to the difference between the self-propulsion speeds, while keeping
    the average self-propulsion speed fixed. A wetting layer rich in fast particles
    arises. The rectification current is amplified by speed diversity due to a superlinear
    dependence of rectification on self-propulsion speed, which arises from cooperative
    effects. Thus, the total rectification current cannot be obtained from an effective
    one-component active fluid with the same average self-propulsion speed, highlighting
    the importance of considering diversity in active matter.

  text: "Data related to the following paper:\r\n\"Stress granules plug and stabilize
    damaged endolysosomal membranes\" (https://doi.org/10.1038/s41586-023-06726-w)\r\n\r\nAbstract:
    \r\nEndomembrane damage represents a form of stress that is detrimental for eukaryotic
    cells. To cope with this threat, cells possess mechanisms that repair the damage
    and restore cellular homeostasis. Endomembrane damage also results in organelle
    instability and the mechanisms by which cells stabilize damaged endomembranes
    to enable membrane repair remains unknown. In this work we use a minimal coarse-grained
    molecular dynamics system to explore how lipid vesicles undergoing poration in
    a protein-rich medium can be plugged and stabilised by condensate formation. The
    solution of proteins in and out of the vesicle is described by beads dispersed
    in implicit solvent. The membrane is described as a one-bead-thick fluid elastic
    layer of mechanical properties that mimic biological membranes. We tune the interactions
    between solution beads in the different compartments to capture the differences
    between the cytoplasmic and endosomal protein solutions and explore how the system
    responds to different degrees of membrane poration. We find that, in the right
    interaction regime, condensates form rapidly at the damage site upon solution
    mixing and act as a plug that prevents futher mixing and destabilisation of the
    vesicle. Further, when the condensate can interact with the membrane (wetting
    interactions) we find that it mediates pore sealing and membrane repair. This
    research is part of the work published in \"Stress granules plug and stabilize
    damaged endolysosomal membranes\", Bussi et al, Nature, 2023 - 10.1038/s41586-023-06726-w."

    Endomembrane damage also results in organelle instability and the mechanisms by
    which cells stabilize damaged endomembranes to enable membrane repair remains
    unknown. Here, by combining in vitro and in cellulo studies with computational
    modelling we uncover a biological function for stress granules whereby these biomolecular
    condensates form rapidly at endomembrane damage sites and act as a plug that stabilizes
    the ruptured membrane. Functionally, we demonstrate that stress granule formation
    and membrane stabilization enable efficient repair of damaged endolysosomes, through
    both ESCRT (endosomal sorting complex required for transport)-dependent and independent
    mechanisms. We also show that blocking stress granule formation in human macrophages
    creates a permissive environment for <jats:italic>Mycobacterium tuberculosis</jats:italic>,
    a human pathogen that exploits endomembrane damage to survive within the host.

  text: The kinetics of the assembly of semiflexible filaments through end-to-end
    annealing is key to the structure of the cytoskeleton, but is not understood.
    We analyze this problem through scaling theory and simulations, and uncover a
    regime where filaments’ ends find each other through bending fluctuations without
    the need for the whole filament to diffuse. This results in a very substantial
    speedup of assembly in physiological regimes, and could help with understanding
    the dynamics of actin and intermediate filaments in biological processes such
    as wound healing and cell division.

  text: The actin cortex is a complex cytoskeletal machinery that drives and responds
    to changes in cell shape. It must generate or adapt to plasma membrane curvature
    to facilitate diverse functions such as cell division, migration, and phagocytosis.
    Due to the complex molecular makeup of the actin cortex, it remains unclear whether
    actin networks are inherently able to sense and generate membrane curvature, or
    whether they rely on their diverse binding partners to accomplish this. Here,
    we show that curvature sensing is an inherent capability of branched actin networks
    nucleated by Arp2/3 and VCA. We develop a robust method to encapsulate actin inside
    giant unilamellar vesicles (GUVs) and assemble an actin cortex at the inner surface
    of the GUV membrane. We show that actin forms a uniform and thin cortical layer
    when present at high concentration and distinct patches associated with negative
    membrane curvature at low concentration. Serendipitously, we find that the GUV
    production method also produces dumbbell-shaped GUVs, which we explain using mathematical
    modeling in terms of membrane hemifusion of nested GUVs. We find that branched
    actin networks preferentially assemble at the neck of the dumbbells, which possess
    a micrometer-range convex curvature comparable with the curvature of the actin
    patches found in spherical GUVs. Minimal branched actin networks can thus sense
    membrane curvature, which may help mammalian cells to robustly recruit actin to
    curved membranes to facilitate diverse cellular functions such as cytokinesis
    and migration.

  text: "Eukaryotic cells use clathrin-mediated endocytosis to take up a large range
    of extracellular cargo. During endocytosis, a clathrin coat forms on the plasma
    membrane, but it remains controversial when and how it is remodeled into a spherical
    vesicle.\r\nHere, we use 3D superresolution microscopy to determine the precise
    geometry of the clathrin coat at large numbers of endocytic sites. Through pseudo-temporal
    sorting, we determine the average trajectory of clathrin remodeling during endocytosis.
    We find that clathrin coats assemble first on flat membranes to 50% of the coat
    area before they become rapidly and continuously bent, and this mechanism is confirmed
    in three cell lines. We introduce the cooperative curvature model, which is based
    on positive feedback for curvature generation. It accurately describes the measured
    shapes and dynamics of the clathrin coat and could represent a general mechanism
    for clathrin coat remodeling on the plasma membrane."

  text: Catalysis, the acceleration of product formation by a substance that is left
    unchanged, typically results from multiple elementary processes, including diffusion
    of the reactants toward the catalyst, chemical steps, and release of the products.
    While efforts to design catalysts are often focused on accelerating the chemical
    reaction on the catalyst, catalysis is a global property of the catalytic cycle
    that involves all processes. These are controlled by both intrinsic parameters
    such as the composition and shape of the catalyst and extrinsic parameters such
    as the concentration of the chemical species at play. We examine here the conditions
    that catalysis imposes on the different steps of a reaction cycle and the respective
    role of intrinsic and extrinsic parameters of the system on the emergence of catalysis
    by using an approach based on first-passage times. We illustrate this approach
    for various decompositions of a catalytic cycle into elementary steps, including
    non-Markovian decompositions, which are useful when the presence and nature of
    intermediate states are a priori unknown. Our examples cover different types of
    reactions and clarify the constraints on elementary steps and the impact of species
    concentrations on catalysis.

  text: Like-charge attraction, driven by ionic correlations, challenges our understanding
    of electrostatics both in soft and hard matter. For two charged planar surfaces
    confining counterions and water, we prove that, even at relatively low correlation
    strength, the relevant physics is the ground-state one, oblivious of fluctuations.
    Based on this, we derive a simple and accurate interaction pressure that fulfills
    known exact requirements and can be used as an effective potential. We test this
    equation against implicit-solvent Monte Carlo simulations and against explicit-solvent
    simulations of cement and several types of clays. We argue that water destructuring
    under nanometric confinement drastically reduces dielectric screening, enhancing
    ionic correlations. Our equation of state at reduced permittivity therefore explains
    the exotic attractive regime reported for these materials, even in the absence
    of multivalent counterions.

  text: By varying the concentration of molecules in the cytoplasm or on the membrane,
    cells can induce the formation of condensates and liquid droplets, similar to
    phase separation. Their thermodynamics, much studied, depends on the mutual interactions
    between microscopic constituents. Here, we focus on the kinetics and size control
    of 2D clusters, forming on membranes. Using molecular dynamics of patchy colloids,
    we model a system of two species of proteins, giving origin to specific heterotypic
    bonds. We find that concentrations, together with valence and bond strength, control
    both the size and the growth time rate of the clusters. In particular, if one
    species is in large excess, it gradually saturates the binding sites of the other
    species; the system then becomes kinetically arrested and cluster coarsening slows
    down or stops, thus yielding effective size selection. This phenomenology is observed
    both in solid and fluid clusters, which feature additional generic homotypic interactions
    and are reminiscent of the ones observed on biological membranes.

  text: Primary nucleation is the fundamental event that initiates the conversion
    of proteins from their normal physiological forms into pathological amyloid aggregates
    associated with the onset and development of disorders including systemic amyloidosis,
    as well as the neurodegenerative conditions Alzheimer’s and Parkinson’s diseases.
    It has become apparent that the presence of surfaces can dramatically modulate
    nucleation. However, the underlying physicochemical parameters governing this
    process have been challenging to elucidate, with interfaces in some cases having
    been found to accelerate aggregation, while in others they can inhibit the kinetics
    of this process. Here we show through kinetic analysis that for three different
    fibril-forming proteins, interfaces affect the aggregation reaction mainly through
    modulating the primary nucleation step. Moreover, we show through direct measurements
    of the Gibbs free energy of adsorption, combined with theory and coarse-grained
    computer simulations, that overall nucleation rates are suppressed at high and
    at low surface interaction strengths but significantly enhanced at intermediate
    strengths, and we verify these regimes experimentally. Taken together, these results
    provide a quantitative description of the fundamental process which triggers amyloid
    formation and shed light on the key factors that control this process.

  text: The sequential exchange of filament composition to increase filament curvature
    was proposed as a mechanism for how some biological polymers deform and cut membranes.
    The relationship between the filament composition and its mechanical effect is
    lacking. We develop a kinetic model for the assembly of composite filaments that
    includes protein–membrane adhesion, filament mechanics and membrane mechanics.
    We identify the physical conditions for such a membrane remodeling and show this
    mechanism of sequential polymer assembly lowers the energetic barrier for membrane
    deformation.

  text: ESCRT-III filaments are composite cytoskeletal polymers that can constrict
    and cut cell membranes from the inside of the membrane neck. Membrane-bound ESCRT-III
    filaments undergo a series of dramatic composition and geometry changes in the
    presence of an ATP-consuming Vps4 enzyme, which causes stepwise changes in the
    membrane morphology. We set out to understand the physical mechanisms involved
    in translating the changes in ESCRT-III polymer composition into membrane deformation.
    We have built a coarse-grained model in which ESCRT-III polymers of different
    geometries and mechanical properties are allowed to copolymerise and bind to a
    deformable membrane. By modelling ATP-driven stepwise depolymerisation of specific
    polymers, we identify mechanical regimes in which changes in filament composition
    trigger the associated membrane transition from a flat to a buckled state, and
    then to a tubule state that eventually undergoes scission to release a small cargo-loaded
    vesicle. We then characterise how the location and kinetics of polymer loss affects
    the extent of membrane deformation and the efficiency of membrane neck scission.
    Our results identify the near-minimal mechanical conditions for the operation
    of shape-shifting composite polymers that sever membrane necks.

  text: Amyloid formation is linked to devastating neurodegenerative diseases, motivating
    detailed studies of the mechanisms of amyloid formation. For Aβ, the peptide associated
    with Alzheimer’s disease, the mechanism and rate of aggregation have been established
    for a range of variants and conditions <jats:italic>in vitro</jats:italic> and
    in bodily fluids. A key outstanding question is how the relative stabilities of
    monomers, fibrils and intermediates affect each step in the fibril formation process.
    By monitoring the kinetics of aggregation of Aβ42, in the presence of urea or
    guanidinium hydrochloride (GuHCl), we here determine the rates of the underlying
    microscopic steps and establish the importance of changes in relative stability
    induced by the presence of denaturant for each individual step. Denaturants shift
    the equilibrium towards the unfolded state of each species. We find that a non-ionic
    denaturant, urea, reduces the overall aggregation rate, and that the effect on
    nucleation is stronger than the effect on elongation. Urea reduces the rate of
    secondary nucleation by decreasing the coverage of fibril surfaces and the rate
    of nucleus formation. It also reduces the rate of primary nucleation, increasing
    its reaction order. The ionic denaturant, GuHCl, accelerates the aggregation at
    low denaturant concentrations and decelerates the aggregation at high denaturant
    concentrations. Below approximately 0.25 M GuHCl, the screening of repulsive electrostatic
    interactions between peptides by the charged denaturant dominates, leading to
    an increased aggregation rate. At higher GuHCl concentrations, the electrostatic
    repulsion is completely screened, and the denaturing effect dominates. The results
    illustrate how the differential effects of denaturants on stability of monomer,
    oligomer and fibril translate to differential effects on microscopic steps, with
    the rate of nucleation being most strongly reduced.
