    Caveolin-1 protects endothelial cells from extensive expansion of transcellular tunnel by stiffening the plasma membrane

    Camille Morel, Eline Lemerle ... Emmanuel Lemichez
    Caveolin-1 controls the width of transendothelial cell tunnels via a direct or indirect effect on membrane bending rigidity.

    Structural basis for the preservation of a subset of topologically associating domains in interphase chromosomes upon cohesin depletion

    Davin Jeong, Guang Shi ... D Thirumalai
    The finding that deletion of the genome folding motor leaves a significant fraction of a key structural feature of chromosome at the single cell and ensemble level has been explained.

    C9orf72 polyPR directly binds to various nuclear transport components

    Hamidreza Jafarinia, Erik van der Giessen, Patrick R Onck
    Length-dependent interference of arginine-containing dipeptide repeat proteins with multiple components of the nucleocytoplasmic transport machinery is a potential mechanistic pathway of C9orf72 amyotrophic lateral sclerosis or frontotemporal dementia toxicity.

    Neural criticality from effective latent variables

    Mia C Morrell, Ilya Nemenman, Audrey Sederberg
    Signatures of criticality that have been observed across diverse neural systems, such as power-law avalanche distributions and exponent relationships, can arise without fine-tuning in networks coupled to latent, dynamical variables.

    A unified approach to dissecting biphasic responses in cell signaling

    Vaidhiswaran Ramesh, J Krishnan
    In-built competing effects are present at different levels in signaling networks, starting from basic biochemical building blocks to the network level, and mathematical and computational analysis reveals when they give rise to biphasic responses and what the consequences are.

    How microscopic epistasis and clonal interference shape the fitness trajectory in a spin glass model of microbial long-term evolution

    Nicholas M Boffi, Yipei Guo ... Ariel Amir
    High-resolution simulations of evolving microbial populations reveal that microscopic epistasis slows the rate of adaptation, while clonal interference can either speed it up or leave it fixed.

    Diameter dependence of transport through nuclear pore complex mimics studied using optical nanopores

    Nils Klughammer, Anders Barth ... Cees Dekker
    Nuclear pore complex mimics based on solid-state nanopores show significant selectivity below a diameter of 55 nm, which decreases gradually for larger pore diameters.

    Energy conservation by collective movement in schooling fish

    Yangfan Zhang, George V Lauder
    Fish schools showed an U-shaped metabolism-speed curve and reduced the energy use per tail beat up to 56% at high swimming speeds compared to solitary fish.
