Research hints at how fungus farming ants keep their gardens healthy

People rely on sight to identify weeds but ants grow fungus underground in the dark and must have other ways to sense undesirable garden denizens. A team led by Jonathan Klassen, Ph.D., at the University of Connecticut and Marcy Balunas, Ph.D., at the University of Michigan has found that the ants sniff out diseased fungus by detecting chemicals called peptaibols.
