Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

Overseeing the research are Prasoon Diwakar, Ph.D. and Timothy Brenza, Ph.D., of the mechanical engineering and chemical and ...

Researchers at Nagoya University developed a phosphonic acid polymer with hydrophobic spacers for fuel cell electrolytes, ...

Kazumitsu Ueda, PhD from Kyoto University, WPI-iCeMS, unveils the mystery of cholesterol homeostasis in this cell biology ...

Osmotic pressure is the force water exerts on the semi-permeable membrane (plasma membrane) surrounding the cell. Water moves across the plasma membrane in response to an unequal distribution of ...

Channels in plant cell walls, called plasmodesmata, provide molecules with a bridge to move between cells, an essential ...

"But having both a bilayer-forming lipid, which provides the basic structure for the cell membrane, and a non-bilayer-forming lipid, such as cholesterol, which adds stability, seems to be a ...

Cytokinesis is the physical separation of two cells that occurs after the completion of mitosis. The mechanism underlying it is very complex. Until recently, the processes that lead to cleavage furrow ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...
