Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary (using quotation marks) in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without quotation marks, if I have any.

On Mars, sands shift to a different drum
The retreat of Mars' polar cap of frozen carbon dioxide during the spring and summer generates winds that drive the largest movements of sand dunes observed on the red planet.

Phase transitions: The math behind the music
"Physics Professor Jesse Berezovsky contends that until now, much of the thinking about math and music has been a top-down approach, applying mathematical ideas to existing musical compositions as a way of understanding already existing music. He contends he's uncovering the 'emergent structures of musical harmony' inherent in the art, just as order comes from disorder in the physical world. He believes that could mean a whole new way of looking at music of the past, present and future."
I'm loving the tone of this summary implying that the press officer doesn't believe any of it.
