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 ...

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 ...

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 ...

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, ...

Cell membranes are thin measuring around 5 nanometers thick and to put that into perspective you could fit about 10,000 membranes across one human hair. However, does understanding a cell membrane's ...
