    Condensation tendency and planar isotropic actin gradient induce radial alignment in confined monolayers

    Tianfa Xie, Sarah R St Pierre ... Yubing Sun
    Radial alignment in confined cell monolayers with isotropic actin network is found to be mediated by the condensation tendency and tissue-scale actin gradient.

    Mechanically transduced immunosorbent assay to measure protein-protein interactions

    Christopher J Petell, Kathyrn Randene ... Joshua P Steimel
    METRIS is a method that reports a mechanical readout of protein-protein interactions and due to its unique properties, it will allow many protein-protein interactions to be quantitatively measured easily that are currently laborious to measure with conventional methods.

    Integrin α5β1 nano-presentation regulates collective keratinocyte migration independent of substrate rigidity

    Jacopo Di Russo, Jennifer L Young ... Joachim P Spatz
    The use of nanopatterned hydrogels and specific integrin α5β1 peptidomimetic revealed that keratinocytes require an optimum inter-ligand spacing to best propagate intercellular forces and efficiently coordinate cell sheet migration.

    A framework for studying behavioral evolution by reconstructing ancestral repertoires

    Damián G Hernández, Catalina Rivera ... Gordon J Berman
    The behavioral repertoires from six species of flies are measured, and a statistical approach is developed to predict co-evolving behaviors, providing a potential framework for exploring behavioral evolution.

    Decoding locomotion from population neural activity in moving C. elegans

    Kelsey M Hallinen, Ross Dempsey ... Andrew M Leifer
    Neurons in the brain exhibit activity with various relations to locomotion and these signals are best decoded by combining activities from many neurons.

    Symmetry breaking meets multisite modification

    Vaidhiswaran Ramesh, J Krishnan
    Network symmetry represents a new vantage point for dissecting complex information processing characteristics in multisite modification, and the breaking of symmetry can confer ordering of modification and absolute concentration robustness.

    A simple regulatory architecture allows learning the statistical structure of a changing environment

    Stefan Landmann, Caroline M Holmes, Mikhail Tikhonov
    Minimal modifications of common regulatory circuits can allow bacteria to learn from the past to better predict the future, on a physiological, rather than evolutionary, timescale.

    Muscle-specific economy of force generation and efficiency of work production during human running

    Sebastian Bohm, Falk Mersmann ... Adamantios Arampatzis
    During human running, the soleus muscle was found to operate as work generator under optimal conditions for work production (high force-length potential and enthalpy efficiency) while the vastus lateralis promoted tendon energy storage and economical force generation (high force-length-velocity potential).

    Hybrid protein assembly-histone modification mechanism for PRC2-based epigenetic switching and memory

    Cecilia Lövkvist, Pawel Mikulski ... Martin Howard
    Extra protein memory storage elements with positive feedbacks, in addition to histone modifications, can explain epigenetic switching and memory at the PRC2 target gene FLOWERING LOCUS C (FLC).
