    Expansion and loss of sperm nuclear basic protein genes in Drosophila correspond with genetic conflicts between sex chromosomes

    Ching-Ho Chang, Isabel Mejia Natividad, Harmit S Malik
    Genetic conflicts between sex chromosomes during spermatogenesis may drive the rapid evolution, function, and turnover of some sperm nuclear basic proteins in Drosophila species.

    Axon tension regulates fasciculation/defasciculation through the control of axon shaft zippering

    Daniel Šmít, Coralie Fouquet ... Alain Trembleau
    Competition between adhesive and tensile forces regulates axon fasciculation, thus introducing a new role of mechanical tension in the development of neural networks.

    Amplitude modulations of cortical sensory responses in pulsatile evidence accumulation

    Sue Ann Koay, Stephan Thiberge ... David W Tank
    From as early as primary visual cortex and across posterior cortical areas, neural responses to visual pulses during an evidence-accumulation task exhibit a multitude of task-related amplitude modulations/gain changes.

    Variable paralog expression underlies phenotype variation

    Raisa Bailon-Zambrano, Juliana Sucharov ... James T Nichols
    Within populations, there is standing variation in paralog expression levels, paralog expression levels are heritable, and variation in paralog expression can modify the phenotypes associated with mutation of one of the paralogs.

    Using population selection and sequencing to characterize natural variation of starvation resistance in Caenorhabditis elegans

    Amy K Webster, Rojin Chitrakar ... L Ryan Baugh
    A powerful sequencing approach is used to elucidate the genetic basis of a complex organismal trait, and members of the irld gene family that affect starvation resistance are identified.

    Pleiotropic effects of trisomy and pharmacologic modulation on structural, functional, molecular, and genetic systems in a Down syndrome mouse model

    Sergi Llambrich, Birger Tielemans ... Greetje Vande Velde
    Ts65dn mice exhibit structural, functional, molecular, and genetic alterations that are modulated but unrecovered by prenatal chronic GTE-EGCG, highlighting the importance of holistic studies to understand complex disorders and treatments.

    Experimental evidence that group size generates divergent benefits of cooperative breeding for male and female ostriches

    Julian Melgar, Mads F Schou ... Charlie K Cornwallis
    Experimental manipulations of social groups of ostriches show that the benefits of cooperative parental care for females, and the costs of sexual competition for males, lead to sex differences in optimal group sizes.

    Host-associated microbe PCR (hamPCR) enables convenient measurement of both microbial load and community composition

    Derek S Lundberg, Pratchaya Pramoj Na Ayutthaya ... Detlef Weigel
    hamPCR is a cost-effective and transformative amplicon sequencing strategy to describe microbiota composition and measure its overall abundance, applicable to all samples in which host and microbial DNA are co-extracted.

    An atlas of neural crest lineages along the posterior developing zebrafish at single-cell resolution

    Aubrey GA Howard IV, Phillip A Baker ... Rosa A Uribe
    Single-cell dissection of recent neural crest derivatives in the vertebrate zebrafish reveals diverse transcriptomic signatures among differentiating posterior cell types during the embryonic to larval stage transition.

    Continuous odor profile monitoring to study olfactory navigation in small animals

    Kevin S Chen, Rui Wu ... Andrew M Leifer
    To study odor-guided navigation of small animals such as worms and fly larvae, a novel flow chamber and odor sensor array are presented that better characterize the odors that the animal experiences.
