    Structure and function of axo-axonic inhibition

    Casey M Schneider-Mizell, Agnes L Bodor ... Nuno Maçarico da Costa
    Electron microcopy-based connectomics, in vivo functional imaging, and biophysical modeling reveal that mouse visual cortex chandelier cells, a type of GABAergic interneuron, are driven by arousal and distribute their synapses according to the individual properties of target cells.

    High-content microscopy reveals a morphological signature of bortezomib resistance

    Megan E Kelley, Adi Y Berman ... Gregory P Way
    Morphological profiling of untreated HCT116 cells using Cell Painting reveals a signature of bortezomib resistance, providing a proof-of-concept for the unbiased analysis of drug resistance.

    Regionally distinct trophoblast regulate barrier function and invasion in the human placenta

    Bryan Marsh, Yan Zhou ... Robert Blelloch
    Single cell RNA-sequencing of distinct regions of the human placenta identifies a smooth chorion-specific cytotrophoblast population responsible for unique functions of the smooth chorion, including acting as a barrier and restricting invasion.

    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.

    Passive accumulation of alkaloids in inconspicuously colored frogs refines the evolutionary paradigm of acquired chemical defenses

    Rebecca D Tarvin, Jeffrey L Coleman ... Richard W Fitch
    The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.

    Experimental evidence that group size generates divergent benefits of cooperative breeding for male and female ostriches

    Julian Melgar, Mads F Schou ... Charlie K Cornwallis
    Experimental manipulations of social groups of ostriches show that the benefits of cooperative parental care for females, and the costs of sexual competition for males, lead to sex differences in optimal group sizes.

    The flagellar motor of Vibrio alginolyticus undergoes major structural remodeling during rotational switching

    Brittany L Carroll, Tatsuro Nishikino ... Jun Liu
    In situ structures of the flagellar motors genetically docked in CCW and CW rotational states reveal major rearrangement that facilitates rotational switch in Vibrio alginolyticus..

    Large-scale orientational order in bacterial colonies during inward growth

    Mustafa Basaran, Y Ilker Yaman ... Askin Kocabas
    When crowded bacterial colonies invade a closed area, flow-induced alignment creates strong radial orientation and leads to the formation of aster defects.

    Sparse activity of identified dentate granule cells during spatial exploration

    Maria Diamantaki, Markus Frey ... Andrea Burgalossi
    Morphologically-mature granule cells with complex dendritic trees contribute to a sparse representation of space in the rat dentate gyrus.

    Structural basis of the effect of activating mutations on the EGF receptor

    Ioannis Galdadas, Luca Carlino ... Francesco Luigi Gervasio
    Computational methods reveal how mutations affect the conformational landscape of the kinase domain of EGFR resulting in abnormal signaling and provide a structural framework for ongoing drug discovery efforts on mutant-specific EGFR inhibition.
