    Genetic and environmental influences on adult human height across birth cohorts from 1886 to 1994

    Aline Jelenkovic et al.
    Genetic variance of adult human height shows a generally increasing trend across the birth-year cohorts but heritability estimates do not present any clear pattern of secular changes over a century.

    Vascular dimorphism ensured by regulated proteoglycan dynamics favors rapid umbilical artery closure at birth

    Sumeda Nandadasa et al.
    Morphologic, molecular, biomechanical and computational analyses show that the specialized extracellular matrix architecture of the umbilical artery contributes to its rapid closure at birth and regulates smooth muscle cell differentiation.

    Coupling adaptive molecular evolution to phylodynamics using fitness-dependent birth-death models

    David A Rasmussen, Tanja Stadler
    A new model describes how adaptive molecular evolution shapes phylogenetic trees and can be used to estimate the fitness effects of mutations from phylogenies.

    A hierarchical, retinotopic proto-organization of the primate visual system at birth

    Michael J Arcaro, Margaret S Livingstone
    A retinotopic proto-organization present at birth provides the infrastructure for the subsequent development of visual cortex that commences at the onset of visual experience.

    Vascular Biology: Severing umbilical ties

    Jessica E Wagenseil, Karen M Downs
    High levels of proteins called proteoglycans in the walls of umbilical arteries enable these arteries to close rapidly after birth and thus prevent blood loss in newborns.

    Point of View: Towards a mechanistic foundation of evolutionary theory

    Michael Doebeli et al.
    A description of evolution that is based on birth-death processes, and in which fitness is at most a derived quantity, is advocated.

    Sex Difference: What does cannabis do to the brain before birth?

    Stefano Musardo, Camilla Bellone
    Being exposed to cannabinoids in the womb has different consequences for male and female rats. .

    Cdon mutation and fetal alcohol converge on Nodal signaling in a mouse model of holoprosencephaly

    Mingi Hong et al.
    A combination of window-of-sensitivity, genetic, and in vitro findings illuminate mechanisms of gene–environment interaction in a multifactorial model of a common birth defect.

    Chronology-based architecture of descending circuits that underlie the development of locomotor repertoire after birth

    Avinash Pujala, Minoru Koyama
    Newly forming descending pathways are arranged to function in parallel to existing ones and contribute to increasingly sophisticated locomotor behaviors that emerge postnatally with suitable connectivity patterns and biophysical properties.
