This is an interesting look at the history and possible futures of understanding life‘s electric current. One of the biggest challenges was finding a way to measure such minuscule voltages, which involve fluctuations of Na, K, and Ca ions. The ‘electrome‘ likely directs a lot of what we don‘t understand about gene expression, symmetry, and cell differentiation. As a nurse I‘m always explaining why electrolytes are important, and this is why: ⚡️
