"For decades, scientists have viewed DNA as the sole source of cellular information."


Well, some of the dumber ones did. Cellular function studies have a long and honored history of stupidity.

Nerve cells communicate with with one another by fiddling local potassium to sodium ion ratios. It changes the voltage difference across the cell-to-cell junctions. The signals can propagate fairly fast.

"In fact, the propagation velocity of the action potentials in nerves can vary from 100 meters per second (580 miles per hour) to less than a tenth of a meter per second (0.22 miles per hour)."

DNA doesn't come into it (or at least not directly).

Science daily was suggesting that regular cells use a similar sort of system for communicating with their near neighbours. Why this would be a "hidden communication system" escapes me. If nobody looked for it, it wouldn't have to be "hidden" to be unknown.
