    Genome-wide association studies of brain imaging data from 8,428 individuals in UK Biobank show that many of the 3,144 traits studied are heritable, and genes associated with individual phenotypes are identified.

    Parental care in mice evolves through multiple genetic changes; one candidate is vasopressin, the reduced expression of which promotes parental nest-building behaviour in monogamous mice.

    Multi-ancestry genome-wide association analyses for birth weight in 153,781 individuals identified 60 genomic loci in which birth weight and fetal genotype were associated and found an inverse genetic correlation between birth weight and cardiometabolic risk.

    The effect of natural genetic diversity on the proteome is characterized using an outbred mouse model with extensive variation; both transcripts and proteins from mouse livers are quantified to identify a large set of protein quantitative trait loci (pQTL), and mediation analysis identifies causal protein intermediates of distant pQTL.

    Quantifying activity of cis-regulatory sequences controlling gene expression shows that selection on expression noise has a greater impact on sequence variation than selection on mean expression level.

    A large-scale analysis of variation in human protein levels between individuals is performed using mass-spectrometry-based proteomic technology, and a number of protein quantitative trait loci are identified; over 5% of proteins vary by more than 1.5-fold in their expression levels between individuals, and this variation is not always linked to RNA level.

    By combining full-genome sequencing and ‘evolutionary replay’ experiments to dissect the origin of aerobic citrate use in an experimental Escherichia coli population over 40,000 generations and 2 decades, the authors unveil a 3-step process in which potentiation makes a trait possible, actualization makes the trait manifest and refinement makes it effective.
