Diffusion is the movement of particles from a region where they are in high concentration to a region where they are in low concentration, and is one of the ways substances can move across the cell ...

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 ...

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 ...

The film discusses the fundamental processes of cell biology, focusing on how cells grow, reproduce, and perform essential life functions through chemical reactions. It explains the distinction ...

Recent studies have revealed that within cells of both yeast and bacteria, the rates of diffusion of RNA proteins - complex molecules that convey important information throughout the cell - are ...

Researchers studying the movement, interactions and microenvironments of intracellular molecules often need to analyze information on the patterns and rates with which molecules diffuse within the ...
