Potassium channels are openings that allow charged potassium atoms to cross the cell membrane. Voltage-gated potassium channels—which open only when a specific voltage is reached across the cell ...

A key approach to understanding the brain is to observe the behavioral effects of turning on specific populations of neurons. One of the most popular approaches to controlling neuronal activity in ...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes various symptoms that go beyond respiratory problems. Neurological, cardiac, and other issues can emerge during infection and after ...

Following this design principle, the researchers create angstrom-scale pores in bi-layer graphene sheets, and decorate the two pore edges with twisted rings of carbonyl groups. The artificial ion ...

Working independently, two European-led research groups may have uncovered an important clue to the mystery of amyotrophic lateral sclerosis (ALS), better known to some as Lou Gehrig or motor neuron ...

Ion selectivity is an important property of cell membrane ion channels. For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready ...

Defying one of biology’s more persistent dogmas, a potassium channel combines functions once thought to be invariably asunder. This channel, which is found in common bacteria, incorporates a subunit ...

Intrigued by the properties of ion channel proteins commonly observed in cells, researchers have developed the first synthetic mechanosensitive potassium channel using a newly developed aromatic ...

For decades, it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers at Goethe University Frankfurt and ...
