Transporting molecules across biological membranes is essential for life. In nature, this can occur through passive transport, known as diffusion. "Biological systems often use mechanical motion to ...

Visualizing the ultrastructure and dynamics of the inner mitochondrial membrane is a major challenge in mitochondrial ...

Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes, regulating ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

All living cells need energy, and most generate it through respiration, a series of chemical reactions normally confined to ...

For the very first time, biologists packed nonliving components into a cell-like membrane, piece by piece, and witnessed the bag of molecules start to behave like life. The lab-made synthetic cell ...

New technique to image single lipids: Lipids are notoriously difficult to detect with light microscopy. Using a new chemical labeling strategy, the Dresden team has overcome this limitation, enabling ...

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 ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach. Until now, scientists could only measure membrane ...
