How living cells solved a needle in a haystack problem to produce electrical signals

Scientists have figured out how cells do the improbable: pick the charged calcium ions out of vast sodium sea to generate electrical signals. The speed and accuracy of this selection is crucial to the beating of the heart and the flow of nerve impulses in the brain. The finding is likely to assist the development of new drugs, such as safer medications for chronic pain.
