    Ancient DNA reveals the lost domestication history of South American camelids in Northern Chile and across the Andes

    Paloma Diaz-Maroto et al.
    aDNA revealed a model of domestication where an ancient guanaco population no longer exists, the loss of the ancient vicuña genetic variation in the modern populations, and frequently interbreeding practices.

    Acquisition of innate odor preference depends on spontaneous and experiential activities during critical period

    Qiang Qiu et al.
    A delicate balance of neural activity is required during critical period in establishing innate odor preference.

    A mobile genetic element increases bacterial host fitness by manipulating development

    Joshua M Jones et al.
    A mobile genetic element provides a selective advantage to host cells by delaying development, including biofilm and spore formation, thereby enabling temporary cheating and extra divisions.

    tTARGIT AAVs mediate the sensitive and flexible manipulation of intersectional neuronal populations in mice

    Paul V Sabatini et al.
    tTARGIT AAVs offer a new approach to manipulate intersectional populations that produce selective and robust transgene expression and are easily modified.

    Integron activity accelerates the evolution of antibiotic resistance

    Célia Souque et al.
    Integrons deploy a variety of adaptive strategies including excision, shuffling, and duplication of cassettes that foster rapid bacterial adaptation and resistance evolution while protecting the genomic integrity of the host.

    Stress resets ancestral heritable small RNA responses

    Leah Houri-Zeevi et al.
    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.

    Systematic functional analysis of rab GTPases reveals limits of neuronal robustness to environmental challenges in flies

    Friederike E Kohrs et al.
    The first complete null mutant collection of all rab GTPase genes in a multicellular organism uncovers neuronal development and function sensitive to environmental challenges in Drosophila.

    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm et al.
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

    The dimeric Golgi protein Gorab binds to Sas6 as a monomer to mediate centriole duplication

    Agnieszka Fatalska et al.
    The dual functional protein, Gorab, associates with the Golgi as a dimer but as a monomer with the procentriole cartwheel protein, Sas6, to mediate centriole duplication.
