An acetylcholine receptor (green) forms a gated ion channel in the plasma membrane. This receptor is a membrane protein with an aqueous pore, meaning it allows soluble materials to travel across the ...

Very unusual atomic states are being produced: Ions are created by removing not just one but 20 to 40 electrons from each atom. These 'highly charged ions' play an important role in current research.

Ever been up in the mountains, at the beach, or in a thunderstorm and suddenly felt a huge change in your mood? That’s not just a feeling of awe. It might be negative ions. Negative ions are molecules ...

The transport of ions is essential to maintain electrophysiological balance on either side of the membrane, called osmotic balance, which is needed for signals to be transduced from their chemical ...
