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.

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.

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

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.

The actomyosin cytoskeleton generates active chiral torques that lead to left-right asymmetry in C. elegans embryos.

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

The pilus extrusion/DNA uptake system of Thermus thermophilus contains a 13-mer of the 757-residue PilQ protein and a tightly bound protein outside the outer membrane with a role in DNA binding.

Free optical steering of spiral waves by attraction-based dragging of their cores in optogenetically modified cardiac tissue.

High-resolution maps and models of the bacterial ribosome provide new chemical insights into protein synthesis, and should enable the development of robust tools for cryo-EM structure modeling and refinement.

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.
