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.

In a breakthrough with promising real-world applications, a team of Rutgers biophysicists, bioengineers, and plant biologists ...

Researchers knew, for instance, that HIV wraps its core viral components in a lipid envelope formed from the host plasma membrane. However, they were uncertain about how HIV controls the remodeling of ...

Discover how a structural breakthrough in the chikungunya virus is opening new avenues for antiviral drug development and ...

Aquaporins are proteins that rapidly transport water across cell membranes while excluding salt. They are critical for maintaining the right balance of water inside and outside cells and for ...

Cell crowding causes high-grade breast cancer cells to become more invasive by activating a molecular switch that causes the cells to shrink and spread.

Image Credit: ART-ur/Shutterstock.com The plasma membrane is the outer layer of a cell, separating it from its environment and regulating molecular exchange. It consists of a lipid bilayer with ...

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 ...

Cells are surrounded by a membrane - the plasma membrane - which acts as a physical barrier but must also be malleable. These ...
