    3D cell neighbour dynamics in growing pseudostratified epithelia

    Harold Fernando Gómez, Mathilde Sabine Dumond ... Dagmar Iber
    The 3D shape and dynamic organization of epithelial cells are far more complex than previously believed, but can be explained with simple physical principles based on lateral surface energy minimisation.

    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon, Sarah E Lower ... Jing-Ke Weng
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    Microevolution of Trypanosoma cruzi reveals hybridization and clonal mechanisms driving rapid genome diversification

    Gabriel Machado Matos, Michael D Lewis ... Björn Andersson
    Unique mechanisms of genetic exchange in the important protozoan pathogen Trypanosome cruzi were characterized in detail using genome analyses of hybrid clones at different time points, showing initial tetraploids followed by genome erosion.

    Gene regulatory network reconstruction using single-cell RNA sequencing of barcoded genotypes in diverse environments

    Christopher A Jackson, Dayanne M Castro ... David Gresham
    Single cell expression data can be used to determine how regulatory transcription factors and target genes are connected, and is especially useful when studying transcription factors controlling heterogeneous cell states.

    Piezo1 ion channels inherently function as independent mechanotransducers

    Amanda H Lewis, Jörg Grandl
    Mechanically activated Piezo1 ion channels, at physiologically relevant densities, behave as independent mechanotransducers, which we propose is essential for homogenous transduction of forces across the entire cell membrane.

    Resting-state fMRI signals contain spectral signatures of local hemodynamic response timing

    Sydney M Bailes, Daniel EP Gomez ... Laura D Lewis
    The frequency content of resting-state fMRI signals contains information that can characterize and predict local variations in hemodynamic response timing which enhances the temporal precision of fMRI.

    Cis-regulatory modes of Ultrabithorax inactivation in butterfly forewings

    Amruta Tendolkar, Anyi Mazo-Vargas ... Arnaud Martin
    CRISPR knock-outs and functional genomic approaches probe the regulatory mechanism restricting the Hox gene Ubx to butterfly hindwings, explaining color pattern differentiation from forewings.

    The testis protein ZNF165 is a SMAD3 cofactor that coordinates oncogenic TGFβ signaling in triple-negative breast cancer

    Zane A Gibbs, Luis C Reza ... Angelique W Whitehurst
    Anomalous expression of the testis protein ZNF165 in cancer cells promotes assembly of a neomorphic transcriptional complex that modulates transcription of TGFβ target genes to support tumor cell survival.

    Targeted memory reactivation in human REM sleep elicits detectable reactivation

    Mahmoud EA Abdellahi, Anne CM Koopman ... Penelope A Lewis
    Sound cues that were associated with memories during wake elicit memory reactivations when replayed to human participants during rapid eye movement sleep, those memory reactivations are identifiable by machine learning models that directly relate electroencephalography patterns of wake and sleep.

    Remodeling of skeletal muscle myosin metabolic states in hibernating mammals

    Christopher TA Lewis, Elise G Melhedegaard ... Julien Ochala
    During hibernation, animals remodel the structure of their relaxed muscle via a protein called myosin and this enables vast temperature changes.
