What is it about?
The positioning of the nucleus in the center of a cell is an important topic. The movement of the cellular membrane can contribute to this positioning. We have simulated on a computer how a micro-sphere behaves inside an spherical cavity, filled with viscous fluid, when the surface of the cavity vibrates. It is shown that, very slowly, it moves to the center of the cavity.

Why is it important?
The positioning of the nucleus of the cell, specially in the early stages of development, has been related to severe deseases. Nevertheless, this work is not about cellular biology. This research tries to find it the movement of the cellular wall can contribute to this positioning of the nucleus in the center of the cell.
