(6/19/97)

Wine and the Heart - A glass of wine may be the healthiest choice if you want to experience the cardioprotetive benefits of moderate alcohol consumption. (6/13/97)

Molecular Ice Cubes - Infrared studies of molecular ice cubes are helping explain hitherto mysterious characteristics of the universal solvent, water. (6/13/97)

No Water on Moon, Try Jupiter - The latest lunar radar images contradict earlier reports of an ice lake on the moon, but further afield, the Galileo probe reports that Jupiter is wet after all. These findings will recast the search for life or prebiotic reactions in the solar system. (6/10/97)

Strain 195, Major Muncher - The identification of a strain of bacterium, coccoid Strain 195, with a taste for tetrachloroethene and other chlorinated ethylene pollutants could lead to new strategies for cleaning up especially toxic water pollution. (6/09/97)
