BOSTON, May 7 (UPI) -- A U.S. study suggests wind blowing over mountain ranges can generate gravity waves that propagate vertically into Earth's upper mesosphere.

Though an experiment hunting for gravitational waves has yet to find any, its null result helps constrain models of how the universe began.
