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 ...

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 ...

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 ...

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, ...

The software allows researchers to do three different types of diffusion studies using Olympus FluoView® confocal microscope systems, providing flexibility for the widest variety of cell biology and ...

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 ...
