    Domestic chickens activate a piRNA defense against avian leukosis virus

    Yu Huining Sun, Li Huitong Xie ... Xin Zhiguo Li
    To protect the germ line genome, chickens acquire new small RNA-based immune defense in response to recently endogenized retroviruses by turning a truncated provirus into a weapon.

    Numerical magnitude, rather than individual bias, explains spatial numerical association in newborn chicks

    Rosa Rugani, Giorgio Vallortigara ... Lucia Regolin
    Spatial numerical association in three-day-old domestic chicks linearly decreases as numerical magnitude increases (2>5>8), supporting the hypothesis that numerical magnitude guides the spatial numerical association.

    A cell atlas of the chick retina based on single-cell transcriptomics

    Masahito Yamagata, Wenjun Yan, Joshua R Sanes
    A molecular atlas of the chick retina provides a comprehensive classification and characterization of 136 cell types, yielding novel insights into retinal structure, function, development, and evolution.

    Detailed analysis of chick optic fissure closure reveals Netrin-1 as an essential mediator of epithelial fusion

    Holly Hardy, James GD Prendergast ... Joe Rainger
    Chick optic fissure closure is a powerful new model system for epithelial fusion and has revealed Netrin-1 as a conserved and essential mediator of tissue fusion in multiple contexts.

    Zygotic gene activation in the chicken occurs in two waves, the first involving only maternally derived genes

    Young Sun Hwang, Minseok Seo ... Jae Yong Han
    In Aves, the first wave of transcription is derived exclusively from the maternal genome.

    Young domestic chicks spontaneously represent the absence of objects

    Eszter Szabó, Cinzia Chiandetti ... Giorgio Vallortigara
    Without specific training, young chicks represent the absence of objects, showing that the concept of 'nothing' is available to nonhuman animals and does not require linguistic tools, such as negation.

    Overriding FUS autoregulation in mice triggers gain-of-toxic dysfunctions in RNA metabolism and autophagy-lysosome axis

    Shuo-Chien Ling, Somasish Ghosh Dastidar ... Don W Cleveland
    Elevating FUS level by saturating autoregulation loop in mice causes aggressive motor neuron disease via disrupting protein and RNA homeostasis.

    A low-tech, cost-effective and efficient method for safeguarding genetic diversity by direct cryopreservation of poultry embryonic reproductive cells

    Tuanjun Hu, Lorna Taylor ... Michael J McGrew
    A simple cryopreservation method using chicken eggs will be a valuable tool to safeguard genetic diversity and conserve the 1600 local breeds of chicken on the planet.

    Paraxial mesoderm organoids model development of human somites

    Christoph Budjan, Shichen Liu ... Sahand Hormoz
    Human somites are formed in organoids from human pluripotent stem cells.

    Expression levels of MHC class I molecules are inversely correlated with promiscuity of peptide binding

    Paul E Chappell, El Kahina Meziane ... Jim Kaufman
    The number of different peptides presented by major histocompatibility complex class I molecules to the immune system's T lymphocytes is inversely correlated with cell surface expression and is strongly associated with the response to infectious disease.
