    Genetic and environmental perturbations lead to regulatory decoherence

    Amanda Lea, Meena Subramaniam ... Julien F Ayroles
    Infection and metabolic syndrome lead to a loss of molecular regulation, and changes in molecular correlations are under genetic control as revealed by the presence of correlation quantitative trait loci.

    Genome-wide quantification of the effects of DNA methylation on human gene regulation

    Amanda J Lea, Christopher M Vockley ... Jenny Tung
    mSTARR-seq identifies regions of the genome where DNA methylation causally impacts gene expression, providing a map of which epigenetic marks may influence trait variation.

    The homo-oligomerisation of both Sas-6 and Ana2 is required for efficient centriole assembly in flies

    Matthew A Cottee, Nadine Muschalik ... Susan M Lea
    The structure of the Ana2 Central Coiled-Coil Domain provides insight into how centriolar cartwheel components may be recruited and assembled, and indicates that cartwheel assembly involves more than just SAS-6 oligomerisation.

    Electric field causes volumetric changes in the human brain

    Miklos Argyelan, Leif Oltedal ... Christopher Abbott
    The electroconvulsive therapy induced electric field magnitude and laterality is related to volumetric increases in cortical and subcortical structures, but the association with clinical outcomes remains elusive.

    Active suppression of a leaf meristem orchestrates determinate leaf growth

    John Paul Alvarez, Chihiro Furumizu ... John L Bowman
    A meristem acting at the margins of Arabidopsis leaves is suppressed by factors acting primarily in leaves and other determinate organs.
    1. Neuroscience

    Hippocampal activation is associated with longitudinal amyloid accumulation and cognitive decline

    Stephanie L Leal, Susan M Landau ... William J Jagust
    Cognitively normal older adults show a positive relationship between neural activity during memory encoding and brain β-amyloid deposition rate over the subsequent 3-4 years, supporting preclinical data that associates neural activity with β-amyloid deposition.

    Cis-activation in the Notch signaling pathway

    Nagarajan Nandagopal, Leah A Santat, Michael B Elowitz
    Activation of Notch receptors by ligands in the same cell (cis-activation) is a prevalent and functional mode of signaling in the Notch pathway, and co-exists with trans-activation and cis-inhibition.

    Stress resets ancestral heritable small RNA responses

    Leah Houri-Zeevi, Guy Teichman ... Oded Rechavi
    Various types of stress reset heritable small RNA responses through the function of the p38 MAPK pathway, the transcription factor SKN-1/Nrf2, and the MET-2/SETDB1 putative histone methyltransferase.

    Reduction of elevated proton leak rejuvenates mitochondria in the aged cardiomyocyte

    Huiliang Zhang, Nathan N Alder ... Peter S Rabinovitch
    The primary respiratory defect seen in aged cardiomyocytes is an elevated proton leak mediated by ANT1, and this is prevented by treatment with SS-31 (elamipretide).

    Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci

    Fan Han, Minal Jamsandekar ... Leif Andersson
    Hundreds of loci underlying ecological adaptation to different environmental conditions show striking differences in allele frequencies between ecotypes of Atlantic herring.
