Diffusion helps to transfer substances between cells. Find out more with Bitesize. For students between the ages of 11 and 14.

Small-scale analysis of RNA diffusion rates throughout cells of yeast and bacteria reveals that rates of change of entropy in certain time intervals are larger in areas with higher diffusion rates ...

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

Animals breathe in oxygen, following which it must be delivered to all the organs in the body. This process involves red blood cells and diffusion.

New work describes vital aspects of diffusion processes in tissue development, including the roles that molecular diffusion gradients have on stem cell signaling pathways along with new modeling ...

It explains that the transition to multi-cellularity was driven by the limitations of diffusion in larger cells, necessitating the formation of smaller, organized units.

Revise the structures of cells and the difference between diffusion, osmosis and active transport. Study the factors that affect enzyme action.

Diffusion processes and local dynamic equilibria inside cells lead to nonuniform spatial distributions of molecules, which are essential for processes such as nuclear organization and signaling in ...

In real life, however, we experience limited diffusion. The spread of a flower’s fragrance in the air and the dissolution of ink in water are examples of diffusion in gaseous and liquid states ...

The software allows researchers to do three different types of diffusion studies using Olympus FluoView® confocal microscope systems.
