We suggest that the cytoskeleton in contact with the inner surface of biological membranes in cells exhibiting tensegrity, may be considered as a system near critical conditions. This feature will influence the dynamical processes, such as diffusion, associated with the membrane’s fluctuations...

We investigate the conformations of single regularly-repeating block copolymer chains with rigidity in a poor solvent. We predict the existence of two novel conformations—the stripey torus and the figure eight, and examine the stability of these theoretically.
