A biologically active process promoting resistance to stress in mice is reported in the online science journal Cell (subscription required). The research was supported by the National Institute of Mental Health (NIMH) and a press release noted, "[T]he researchers found differences in the rate of impulse-firing by cells that make the chemical messenger dopamine."
