    Left hemisphere dominance for bilateral kinematic encoding in the human brain

    Christina M Merrick, Tanner C Dixon ... Richard B Ivry
    An electrode-wise encoding model based on physiological recordings from the cortical surface revealed a striking hemispheric asymmetry where the encoding of ipsilateral movement was stronger in the left hemisphere compared to the right hemisphere.

    Testosterone pulses paired with a location induce a place preference to the nest of a monogamous mouse under field conditions

    Radmila Petric, Matina Kalcounis-Rueppell, Catherine A Marler
    Transient increases in the hormone testosterone shift behavioral focus by influencing both spatial preference and vocalizations of a monogamous and biparental mouse in the wild.

    β-cell deletion of the PKm1 and PKm2 isoforms of pyruvate kinase in mice reveals their essential role as nutrient sensors for the KATP channel

    Hannah R Foster, Thuong Ho ... Matthew J Merrins
    Local ATP production by the plasma membrane-associated glycolytic enzyme pyruvate kinase is essential for the nutrient-dependent closure of the ATP-sensitive potassium channels that initiate insulin release from pancreatic β-cells.

    Directed differentiation of human iPSCs to functional ovarian granulosa-like cells via transcription factor overexpression

    Merrick D Pierson Smela, Christian C Kramme ... George M Church
    Making human stem cells express certain transcription factors can convert them into cells that are similar to ovarian granulosa cells, and perform several important functions of the ovary.

    Novel regulators of islet function identified from genetic variation in mouse islet Ca2+ oscillations

    Christopher H Emfinger, Lauren E Clark ... Alan D Attie
    Analysis of islet calcium oscillation responses will provide the field with a resource with which to determine the strain of interest for their specific islet biology questions.

    Metrics of high cofluctuation and entropy to describe control of cardiac function in the stellate ganglion

    Nil Z Gurel, Koustubh B Sudarshan ... Olujimi A Ajijola
    Networked cardiac control, revealed through analysis of extended baseline-state multi-channel recordings, differentiates heart failure and normal regimes highlighting the promise of peripheral neurally based clinical interventions.

    Multicolor fluorescence fluctuation spectroscopy in living cells via spectral detection

    Valentin Dunsing, Annett Petrich, Salvatore Chiantia
    Fluorescence fluctuation spectroscopy is implemented for detection of up to four molecular species, allowing users to quantify molecular interactions and stoichiometry of multicomponent complexes in live cells, in a wide range of biological processes, from membrane signaling to viral assembly.

    Rarity is a more reliable indicator of land-use impacts on soil invertebrate communities than other diversity metrics

    Andrew Dopheide, Andreas Makiola ... Ian A Dickie
    Rarity metrics reveal pervasive negative impacts of agricultural land use on soil invertebrate communities, whereas widely-used richness and diversity metrics underestimate the magnitude of these impacts.

    Evolutionary druggability for low-dimensional fitness landscapes toward new metrics for antimicrobial applications

    Rafael F Guerrero, Tandin Dorji ... C Brandon Ogbunugafor
    Inspired by notions of 'druggability' from medicinal chemistry, two new metrics, drug applicability and variant vulnerability, utilize evolutionary perspectives and methods to improve attempts to treat infectious diseases.
