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 ...

SODIUM and potassium concentrations in human red cells are controlled by the sodium pump, and if passive leaks exceed rates of active transport cells undergo colloid osmotic haemolysis. Because the ...

For decades it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers have now elucidated the transport path ...

Lignin is an abundant aromatic polymer found in plant secondary cell walls. In recent years, lignin has attracted renewed interest as a feedstock for bio-based chemicals via catalytic and biological ...

During osmotic changes of their environment, cells actively regulate their volume and plasma membrane tension that can passively change through osmosis. How tension and volume are coupled during ...
