Repeated evolution of eye regression in subterranean mammals helps identify genes and regulatory elements involved in visual perception and development of the eye, and predicts candidate sequences with a potential role in ocular disorders.
Despite evidence of retinal stretching with eye growth, cone photoreceptor sampling density in the foveal center of humans actually increases with eye length.
Biochemical and structural studies uncover an unexpected mode of interaction, with unprecedented high affinity, between INAD scaffold and NORPA that is critical for Drosophila compound eye photo-transduction.
Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.
Contrary to the high absolute number of white-eyes in other parts of the world, the Indonesian archipelago is the center of phylogenetic diversity of this great speciator.
Bigger bumblebee eyes have better vision, yet their field of view, sensitivity, and resolution do not all simply scale up with eye size, being improved locally instead.
Improved 3D and 4D imaging of neurovascular processes across scales reveals new insights into eye disease mouse models and shows retinal vessels are significantly distorted using standard flat-mount confocal imaging.
By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.
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.
