Human voices convey meaning and emphasis by changing pitch. Now, scientists at University of California, San Francisco believe they have found the brain area that makes this possible.
Scientists increasingly believe home sapiens achieved language not only by evolving a sophisticated larynx, or voice box, but also by developing the neurological capacity to use it in a variety of ways.

A new study suggests that a geologic “pressure release valve” in California’s San Andreas Fault might work more sporadically than previously thought, putting more stress on neighboring segments to the north and south.
When the next Mars rover launches in 2020, it will sport a sidekick: a football-sized scout helicopter.
Mars’s atmosphere is 1 percent as dense as Earth’s, so the copter will have to fly at the equivalent of 100,000 feet — 60,000 feet higher than any Earth-bound chopper has ever flown.
A team of researchers at University of Arizona and the University of Toronto have published a study of a rare dementia called primary progressive aphasia, or PPA.
The research linked improved patient outcomes to the brain’s capacity to “recruit” other areas of the brain to make up for deficits.
