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 ...

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, ...

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 ...

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 ...

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 ...
