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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

Copley Scientific’s new Vertical Diffusion Cell Test System Model HDT 1000 comprises a compact unit with 10 test stations that enables the precise control of test conditions. Copley Scientific’s new ...

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 ...
