Instead of looking at a single gene or protein in isolation, researchers may one day study all of them at once to understand how the body functions and how things go wrong, charting for the first time the intricate biochemical chain reactions that lead to heart disease, diabetes or schizophrenia--and gaining astonishing insights into cures.

They do so by starting chain-reactions that result in the addition and subtraction of molecular sub-units known as phosphate groups from particular proteins in the nerve cell being stimulated.
