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.

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

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

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.

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.

The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.

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.

Mitochondrial anti-viral signaling proteins form three-stranded helical filaments in launching innate immune responses against RNA viruses.
