When Earth is studied from space, its surface looks smooth, but on zooming in we notice the mountains and valleys. The same applies to cells; without magnification they look smooth, but a closer look reveals both ridges and craters.
Researchers from the Universities of Gothenburg and Uppsala, Sweden, studied how this variation in cell topography affects "diffusion" -- how molecules move in the cell membrane. Diffusion is studied to develop models for the membrane's organization and to increase our understanding on the interaction between cell components.

The basis for the researchers' study was their previous discoveries. These showed that not a single one of 70 cell types studied has a smooth surface.
"Today's dominant models of how the plasma membrane that surrounds the cell is organized are based on...
