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 prokaryotes, ...

From the fluid mosaic model to tight junctions, cell membranes are the ultimate gatekeepers of life. They manage what comes in and out, maintain balance, and even signal to other cells. Understanding ...

The cell membrane’s hidden complexity Far from being a static shell, the cell membrane is a fluid, selectively permeable phospholipid bilayer embedded with proteins, carbohydrates, and cholesterol. It ...

Researchers shifted the focus to the internal properties of the membrane itself, specifically its viscosity, highlighting its critical role in controlling deformation and dynamics during essential ...

A new computational study led by University at Buffalo scientists and published April 21 in Biophysical Journal sheds light ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...

Think back to that basic biology class you took in high school. You probably learned about organelles, those little “organs” inside cells that form compartments with individual functions. For example, ...

Found in complex living organisms, TOR acts as a conductor, integrating signals such as nutrient availability, energy levels, ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...
