A premature baby is touched through an incubator at the Sourasky Medical Center in Tel Aviv, Israel, Thursday, Dec. 10, 2009. Doctors at the center measured the energy expenditure of 20 infants born preterm while listening to Mozart in their incubator and compared it to the amount of energy they spent without the music. Their findings showed Mozart lowered the energy they used, meaning the babies may be able to stabilize their weight faster. (AP Photo/Ariel Schalit)
