A molecular motor is made of either a single macromolecule or a macromolecular complex.
Just like their macroscopic counterparts, molecular motors “transduce” input energy into …

Interkinetic nuclear migration (INM), the movement of neuroepithelial and radial glial cell
nuclei along the apical-basal axis in concert with the cell cycle, underlies the …

Cells are filled with macromolecules and polymer networks that set scale-dependent viscous
and elastic properties to the cytoplasm. Although the role of these parameters in molecular …

Both at a basal level and after induction (especially in response to nutrient starvation), the
function of autophagy is to allow cells to degrade and recycle damaged organelles, proteins …

The mitotic spindle assembles to a steady-state length at metaphase through the integrated
action of molecular mechanisms that generate and respond to mechanical forces. While …

The subcellular events occurring in cells of legume plants as they form transcellular
symbiotic-infection structures have been compared with those occurring in premitotic cells …

Recent experiments suggest that microtubules do not grow steadily but instead elongate at a
rate that varies in time. We argue that this variation might arise from fluctuations in the length …

Brain homeostasis relies on the selective permeability property of the blood brain barrier
(BBB). The BBB is formed by a continuous endothelium that regulates exchange between …

The emerging science of biotensegrity provides a fresh context for rethinking our
understanding of human movement, but its complexities can be formidable. Biotensegrity …

At the onset of division, the cell forms a spindle, a precise self-constructed micromachine
composed of microtubules and the associated proteins, which divides the chromosomes …
