Serenading Cells with Audible Sound Alters Gene Activity
The cells in your ears aren’t the only ones listening: recent research suggests that crucial cells throughout the body may respond to audible sound. Experiments described in Communications Biology revealed more than 100 genes whose activity changed in response to these acoustic waves, pointing to possible medical applications. Extensive earlier research has shown that ultrasound—sound at frequencies higher than humans can hear—can affect biology in numerous ways; the new study expands this conc
