It is hypothesized that the magnetic field acts directly on the microtubules of the mitotic apparatus, resulting in changes in cleavage-furrow geometries that provide a clear example of a static magnetic-field effect on a fundamental cellular process, cell division.

Swimming Paramecium in magnetically simulated enhanced, reduced, and inverted gravity environments
A magnetic force-based technique is demonstrated that is unique in its capability to enhance, reduce, and even invert the effective buoyancy of cells and thus simulate hypergravity, hypogravity, and inverted gravity environments and establishes a general technique for applying continuously variable forces to cells or cell populations suitable for exploring their force transduction mechanisms.
Evidence for two extremes of ciliary motor response in a single swimming microorganism.
Aligning Paramecium caudatum with static magnetic fields.
It is suggested that magnetic fields can be exploited as a novel, noninvasive, quantitative means to manipulate swimming populations of unicellular organisms.

A study of the microscopic structure and properties of the striped patterns that spontaneously form in polymerizing tubulin solutions and a mechanism driving this assembly is proposed, revealing a unique physical chemical mechanism by which mechanical buckling couples with protein polymerization to produce macroscopic patterns.
