The Pk^pk and Pk^sple isoforms of the Prickle protein determine right- or left-handed bristle morphogenesis by coupling Frizzled/Vang signaling to the Fat/Dachsous PCP directional signal in opposite directions.

Developmentally controlled chiral counter-rotating actomyosin flows drive cell-lineage spindle skews and cell rearrangements during cytokinesis in early nematode development.

Left-right asymmetric rotation of the Drosophila hindgut is driven by "cell sliding," a novel cellular behavior induced by chiral cell deformation, in which cells change their position relative to subjacent neighbors as sliding directionally.

The great pond snail is a multipurpose model organism and a contemporary choice for addressing a wide range of biological questions, problems and phenomena in the laboratory and the field.

Drawing may be a way to better understand a biological process and to explore and develop scientific ideas.

Large-scale in vivo imaging of the zebrafish left-right organizer (Kupffer's vesicle) combined with fluid dynamics calculations allows to quantitatively test the possible flow detection mechanisms and supports the flow transport of chemical signals as the mechanism of side determination.

Distinct molecular functions contribute to the same material property at larger scales leading to degenerate functionality.

A genetic screen and live cell imaging show that a newly identified coiled-coil protein called SAS-7 is the earliest acting factor in centriole assembly yet identified in the roundworm Caenorhabditis elegans.

LAMP proteins, the major glycoproteins of the lysosome membrane, bind cholesterol directly and specifically, and interact with NPC1 and NPC2 proteins as part of the lysosomal cholesterol export process.

Mammalian sperm subject to shear flow swim in upstream spirals along the walls bounding such flows, thereby demonstrating a robust mechanism for upstream navigation to the ovum.
