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 ...

Determining the properties of biomolecules—particularly of proteins—in their natural environment is a critical step in analyzing their functions and elucidating the mechanisms behind cellular and ...

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 tools ...

The film explores the evolution of multi-celled animals, particularly sponges, from single-celled organisms like amoebas. It explains that the transition to multi-cellularity was driven by the ...

Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, ...

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 ...

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 ...
