New fundamental physics research provides insights on the process of diffusion in complex systems such as living organisms. This new theoretical framework has broad implications for active surfaces, ...

The rate of chemical processes in cells is dictated by the speed of movement (diffusion) of molecules needed for a given reaction. Using a new versatile method, researchers were able to predict for ...

The plasma membrane is what isolates the cell’s interior from its surroundings. It is made up of a lipid bilayer and other macromolecules, such as carbohydrates, glycoproteins, and membrane proteins, ...

A drop of food coloring slowly spreading in a glass of water is driven by a process known as diffusion. While the mathematics of diffusion have been known for many years, how this process works in ...
