NOISES ON  Premature babies in incubators may benefit from recordings of their mothers’ voices and heartbeats, a new study suggests. 

COSMIC SHAKE-UP  Colliding black holes send ripples through spacetime that can be detected on Earth. The Advanced Laser Interferometer Gravitational-Wave Observatory, or Advanced LIGO, which has detectors in Louisiana and Washington,  has directly observed these gravitational waves.
