A cytokinesis checkpoint requiring the yeast homologue of an APC-binding protein
Article Abstract:
The cell-division cycle is regulated by checkpoint controls. Yeast may have a mutation in dynein, a motor protein, and this means that there is often a misalignment of the mitotic spindle, which leads to a delay in cytokinesis until the spindle has found its correct position. Mutuations exist that can abolish the delay and this indicates a new checkpoint control. One checkpoint mechanism appears to be activated by cold temperature which causes mitotic spindles to become misaligned.

Microscopic artificial swimmers
Article Abstract:
A demonstration that a linear chain of colloidal magnetic particles linked by DNA and attached to a red blood cell could act as a flexible artificial flagellum is presented. Results reveal that the actuation induces a beating pattern that propels the structure, and that the external fields could be adjusted to control the velocity and the direction of motion.
