Sticky spots on cell membranes hold onto the master regulator of cell polarity, helping to ensure that the regulatory protein accumulates in high enough concentrations to trigger cell polarity. Over ...

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, ...

This paper seeks to identify the factors which have the greatest effect on gas diffusion rates into animal burrows, and in turn on the maximum size of burrowing animals which may rely on simple burrow ...

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 ...
