Scientists at the University of Geneva are probing the effect of music on brain development in infants who are born prematurely. Their results indicate that listening to music through headphones rather than just hearing ambient noise of the NICU may prompt the babies’ brains to develop more like those of full-term babies. Researchers partnered with an award-winning composer to create a series of soundscapes based on the instruments the infants preferred when they were waking up, falling asleep, or alert and active in their incubators.

Yellow-legged gull (Larus michahellis) chicks have been shown to alter their development after hearing alarm calls from adults outside the egg that signal the presence of predators such as mink, according to researchers in Spain. CREDIT: ALBERTO VELANDO AND JOSE NOGUERA

Researchers in Australia first noted in 2014 that zebra finches produce a form of vocal panting when exposed to heat. Although they sometimes make the call in the presence of other adults or when alone, they most often do it when incubating their young, leading researchers to suspect that the parents may be feeding information to their developing embryos.

Scientists at Geneva University are probing the effect of music on brain development in infants that are born prematurely and housed in the neonatal intensive care unit (NICU). To do so, they partnered with an award-winning composer to create soundscapes based on instruments that the babies liked most—namely the harp, snake flute, and bells.

After 17,000 years, the oldest known conch shell horn has made music once again, playing three notes close to C, D, and C sharp. Image credit: Hypothetical representation of the conch horn in use.
