    Modularity, criticality, and evolvability of a developmental gene regulatory network

    Berta Verd, Nicholas AM Monk, Johannes Jaeger
    A new approach focusing on dynamic modularity helps overcome traditional challenges detecting modularity in complex adaptive systems.

    Mechanisms underlying the response of mouse cortical networks to optogenetic manipulation

    Alexandre Mahrach, Guang Chen ... David Hansel
    Combining experimental and theoretical approaches reveals the interplay between optogenetic manipulation and recurrent interactions in mouse cortex.
    1. Neuroscience

    Neuronal sequences during theta rely on behavior-dependent spatial maps

    Eloy Parra-Barrero, Kamran Diba, Sen Cheng
    A computational framework and analysis of rodent CA1 data reveals that theta oscillations sequentially sweep through the past, present, and future at a spatial scale that varies with the characteristic speed of the animal.

    The selective estrogen receptor downregulator GDC-0810 is efficacious in diverse models of ER+ breast cancer

    James D Joseph, Beatrice Darimont ... Jeffrey H Hager
    GDC-0810 is a novel, orally bioavailable SERD that exhibits robust pre-clinical activity in models of ER+ breast cancer, including models of tamoxifen resistance, and those that express the ERα mutations, ER.Y537S and ER.D538G.

    A Permian fish reveals widespread distribution of neopterygian-like jaw suspension

    Thodoris Argyriou, Sam Giles, Matt Friedman
    μCT-aided study illuminates the cranial endoskeleton and interrelationships of the Permian actinopterygian †Brachydegma, which is now excluded from crown neopterygians despite exhibiting a double jaw joint.

    Epistasis facilitates functional evolution in an ancient transcription factor

    Brian PH Metzger, Yeonwoo Park ... Joseph W Thornton
    A complete mutational scan of a protein-DNA interface shows that pairwise epistatic interactions among amino acids determine a transcription factor's specificity for DNA and facilitate the evolution of new functions.

    Microbiota functional activity biosensors for characterizing nutrient metabolism in vivo

    Darryl A Wesener, Zachary W Beller ... Jeffrey I Gordon
    A method has been developed to characterize the expressed biochemical activities of gut microbial communities using retrievable, microscopic, fluorescent-labeled glass beads containing chemically bound surface biomolecules.

    Nomadic-colonial life strategies enable paradoxical survival and growth despite habitat destruction

    Zhi Xuan Tan, Kang Hao Cheong
    By modelling organisms that alternate between individual and colonial lifestyles, the well-known Parrondo's paradox can emerge in an ecological setting without the need for stochastic environmental variation.

    How to assemble a scale-invariant gradient

    Arnab Datta, Sagnik Ghosh, Jane Kondev
    Intracellular protein gradients, which are formed by the combined action of cytoplasmic diffusion and cortical transport toward the cell pole, are solely determined by cell shape.
    1. Neuroscience

    Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

    Noga Mosheiff, Yoram Burak
    The neural representation of position in the medial entorhinal cortex may be stabilized by synaptic connectivity across modules, which enforces coherent updates in their states.
