Scientists discover signalling circuit boards inside body's cells

Cells in the body are wired like computer chips to direct signals that instruct how they function, research from the University of Edinburgh suggests. Unlike a fixed circuit board, however, cells can rapidly rewire their communication networks to change their behavior. The discovery of this cell-wide web turns our understanding of how instructions spread around a cell on its head.
