    Native American genetic ancestry and pigmentation allele contributions to skin color in a Caribbean population

    Khai C Ang, Victor A Canfield ... Keith C Cheng
    Analysis of 458 Kalinago provides new insights into the population's genetic structure, the contribution of Native American ancestry to skin pigmentation, and the identification of a coding variant in OCA2 with an estimated –8 melanin units effect size.

    Partial connectomes of labeled dopaminergic circuits reveal non-synaptic communication and axonal remodeling after exposure to cocaine

    Gregg Wildenberg, Anastasia Sorokina ... Bobby Kasthuri
    3D serial electron microscopy reveals that individual dopamine axons in the nucleus accumbens contain different varicosity types based on their vesicle contents, rarely make synapses, and undergo major structural plasticity in response to cocaine.

    Age and diet shape the genetic architecture of body weight in diversity outbred mice

    Kevin M Wright, Andrew G Deighan ... Anil Raj
    Genetic effects on body weight in mice are highly heterogeneous, dynamic, and nonlinear with respect to genomic background, age, and diet.

    The retrotrapezoid nucleus neurons expressing Atoh1 and Phox2b are essential for the respiratory response to CO2

    Pierre-Louis Ruffault, Fabien D'Autréaux ... Christo Goridis
    The location of neurons responsible for increasing the breathing rate upon detecting elevated levels of CO2 in the blood has been pinpointed to the retrotrapezoid nucleus in the brainstem.
