The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts. That's still the case, for the most part, but ...

Living cells may generate electricity through the natural motion of their membranes. These fast electrical signals could play ...

The constant, energy-driven motion inside living cells may generate electricity in a way no one fully recognized before.

Our cells may literally ripple with electricity, acting as a hidden power supply that could help transport materials or even ...

Synaptic vesicles act as the brain’s chemical couriers, transporting neurotransmitters between cells. When a nerve impulse arrives, these vesicles fuse with the neuron’s membrane and release their ...

Researchers have developed a theoretical framework that shows how living cell membranes can generate electricity from molecular fluctuations. The work is published in the journal PNAS Nexus. Subscribe ...

When triggered by an odor, rapid changes in membrane voltage and intracellular calcium ion levels occur in nematode olfactory neurons, causing membrane voltage sensors and calcium ion sensors to ...

Axons are the brain’s information highways, transporting cellular cargo, chemical signals, and electrical impulses to other cells. These “roads” are typically depicted as smooth and cylindrical, with ...

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 ...
