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.

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.

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.

By integrating multiplexed error-robust fluorescence in situ hybridization (MERFISH), deep learning, optical sectioning, and protocol optimization, thick-tissue 3D MERFISH allows volumetric single-cell transcriptome imaging of thick-tissue samples, broadening the scope of applications of spatial genomics.

The expression of DECTIN-2 family C-type lectin receptors on macrophages and monocytes is inhibited by the Th2 cytokine IL-4, which suggests a mechanism for inhibition of Th17 responses to MINCLE-dependent vaccination responses by underlying helminth infection.

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.

In vivo quantitative magnetic resonance imaging at ultra-high magnetic field reveals systematic differences of relaxation parameters (R₁) within the human secondary visual cortex at the level of the thin-thick-pale stripes system, which points toward higher cortical myelination of pale stripes.

The Frank–Starling law of the heart and its underlying mechanism of length-dependent activation involve distinctive structural changes in both the thin and thick filaments of cardiac muscle cells.

A single-cell transcriptomic resource of the early chick epiblast from mid-gastrulation through neurulation highlighting emergence of the neural plate border territory, with emphasis on neural crest specification.

mRNA profiling alone provides an incomplete picture of molecular aging and examination of changes in proteins is essential to understand aging processes that are not transcriptionally regulated.
