Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

Mitochondria are cell organelles surrounded by a double membrane. In addition to numerous essential functions in the metabolism of the cell, they also play a key role in the integration of signals ...

Biological processes that govern our lives are many, intertwined, and often difficult to understand. They involve countless ...

A study could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. A new ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...

Cellular membrane proteins play important roles in cellular transport, signaling, and cell-to-cell communication. Malfunction in membrane proteins can lead to serious diseases, such as cancer. However ...

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, ...

‘Tiny biological batteries’ can change the cell membrane’s electrical properties – a discovery that has big implications for health, as many essential cellular processes hinge upon precise electrical ...

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical ...
