Research being conducted at Rush-Presbyterian-St. Luke's Medical Center in Chicago has provided doctors here with a glimpse into how the dreams of those who are depressed from a recent divorce may contribute to overcoming depression.

Some ethnic differences in lung cancer rates linked to nicotine metabolism
Chinese-American smokers draw in less nicotine per cigarette and also metabolize nicotine more slowly than Latinos and other Caucasians, helping explain why they tend to smoke less than most Caucasians and have relatively low rates of lung cancer, UCSF scientists have found.
