New role for cholesterol-lowering drugs
Drugs that lower cholesterol benefit patients who have just had a heart attack or chest pains, regardless of the patient's initial cholesterol levels.

It’s that time. . .for heart attacks?
A small study of young women already at high risk of having a heart attack suggests that heart attacks are most frequent when estrogen levels are low, soon after a woman's period begins.

Big meals boost heart attack risk
Unusually heavy meals boost a person's chance of developing a heart attack, at least among those people who already have risk factors for heart disease.

Sputum Test May Predict Lung Cancer
By zeroing in on aberrations in two cancer-fighting genes, researchers have found a marker for cancer risk that could help doctors screen people for signs of lung cancer early enough for treatment to be effective.

Caffeine may ward off Parkinson’s
Scientists may have found an explanation for why coffee drinking prevents Parkinson's disease.
- Health & Medicine
A vaccine to help ex-smokers
By generating antibodies that neutralize nicotine, a vaccine could keep ex-smokers from getting the nicotine high that drives many of them back to their bad habit.
