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 ...

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

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents ...

Electricity has always been central to how life works, from the firing of neurons to the beating of the heart, but new ...

Membranes are constantly bending as a result of heat fluctuating randomly through the cell. In theory, any voltage produced this way ought to cancel out in environments under equilibrium, making them ...

Biologists have long treated cell membranes as passive barriers, thin skins that separate the chemistry of life from the ...

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

The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, and ...

Alzheimer's is a devastating disease that results in memory loss and cognitive decline. It's caused by brain cells dying and the brain itself shrinking from a buildup of proteins. Millions of seniors ...

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 ...
