    Multiplexed microfluidic screening of bacterial chemotaxis

    Michael R Stehnach, Richard J Henshaw ... Jeffrey S Guasto
    A multiplexed microfluidic device was developed to facilitate high-throughput screening of bacterial chemotaxis on a single chip and demonstrated across a range of microbes, chemostimulants, and chemical gradient conditions.

    Spatial determination and prognostic impact of the fibroblast transcriptome in pancreatic ductal adenocarcinoma

    Wayne Croft, Hayden Pearce ... Paul Moss
    Profiling spatially defined fibroblasts in the pancreatic ductal adenocarcinoma (PDAC) tumor microenvironment identifies high levels of podoplanin and hypoxia in tumor-proximal fibroblasts associated with bad prognosis, whilst inflammatory markers define more distal fibroblast regions and associate with better outcomes.

    Mitochondrial MICOS complex genes, implicated in hypoplastic left heart syndrome, maintain cardiac contractility and actomyosin integrity

    Katja Birker, Shuchao Ge ... Rolf Bodmer
    Genes of the MICOS complex are a major candidate pathway to be potentially linked to defects in cardiomyocyte growth and differentiation in Hypoplastic left heart syndrome (HLHS), and relevant for elucidating the polygenic nature of HLHS and other CHDs.

    Structure of the HIV immature lattice allows for essential lattice remodeling within budded virions

    Sikao Guo, Ipsita Saha ... Margaret E Johnson
    Proteins locked into the immature HIV lattice can exploit its incomplete structure to form the essential protease dimer needed for viral maturation.

    Photoreceptor disc incisures form as an adaptive mechanism ensuring the completion of disc enclosure

    Tylor R Lewis, Sebastien Phan ... Vadim Y Arshavsky
    Maturation of light-sensitive 'disc' membranes in vertebrate photoreceptors requires a precise balance between their content of the visual pigment rhodopsin forming the disc body and tetraspanin proteins forming the disc rim.

    Theta-phase-specific modulation of dentate gyrus memory neurons

    Bahar Rahsepar, Jacob F Norman ... John A White
    Consistent with an existing computational model of hippocampal function, using real-time feedback to drive artificial memories at the trough of the hippocampal theta rhythm improves apparent recall.

    Phosphorylation of tyrosine 90 in SH3 domain is a new regulatory switch controlling Src kinase

    Lenka Koudelková, Markéta Pelantová ... Daniel Rösel
    The functional role of novel regulatory mechanism within prototypic oncogenic kinase c-Src is described with particular emphasis on cancer cell migration, invasiveness, oncogenic transformation, and multilevel regulation of Src itself.

    Recapitulation of pathophysiological features of AD in SARS-CoV-2-infected subjects

    Elizabeth Griggs, Kyle Trageser ... Giulio Maria Pasinetti
    New evidence of brain proinflammatory cascades supports post-acute sequelae of SARS-CoV-2 infection, ultimately promoting the onset and progression of Alzheimer's disease as a function of age.

    Contrasting action and posture coding with hierarchical deep neural network models of proprioception

    Kai J Sandbrink, Pranav Mamidanna ... Alexander Mathis
    To isolate and study proprioception, hierarchical deep neural networks paired with biomechanical models provide a normative approach to test the role of task effects on neural representations, such as the emergence of kinematic tuning and higher-level abstractions of actions.

    Fluid extraction from the left-right organizer uncovers mechanical properties needed for symmetry breaking

    Pedro Sampaio, Sara Pestana ... Susana Santos Lopes
    Zebrafish have a physiological time-window of 1 hr for breaking left-right symmetry and are highly sensitive to the left-right organizer anterior fluid mechanics rather than to the nature of its fluid content.
