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, ...

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 ...

The cloning of green fluorescent protein (GFP), engineering of chimeric fusion proteins, and advances in fluorescence imaging methods have made it possible for researchers to follow the dynamics and ...

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 ...
