Humpback whales, like the one pictured here off the coast of Provincetown, Massachusetts, are routinely located by analyzing when their calls reach underwater microphones. In a recent paper, oceanographer John Spiesberger and a colleague identified a theoretical wave-interference effect that can make energy from sound waves outrun fundamental speed limits without violating the laws of physics. Their findings could improve whale tracking.
