this is a corn root growing in a gel medium under the influence of a very weak DC electromagnetic field. normally the root would grow straight down. A is taken 3hr after the field started being applied, and B was taken 24hr after the field stopped being applied. note how the B root has just started growing downwards again. FROM:
