Plenty of people struggle to make sense of a multitude of converging voices in a crowded room. Commonly known as the 'cocktail party effect,' people with hearing loss find it's especially difficult to understand speech in a noisy environment. New research suggests that, for some listeners, this may have less to do with actually discerning sounds. Instead, it may be a processing problem in which two ears blend different sounds together - a condition known as binaural pitch fusion.

After a one-day delay to wait for improved conditions in the offshore abort zone, SpaceX and NASA are set to launch four astronauts at 5:49 a.m. EDT (0949 GMT) Friday aboard a Falcon 9 rocket and Crew Dragon spaceship from Kennedy Space Center in Florida. The astronauts will dock with the International Space Station early Saturday for a planned six-month mission.
