science news 24.5.2019

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.


astrobiology

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.

the birds and the bees

These fruit bats trade food for sex

Older male crickets attract more females -- but have less sex


climate change

Widespread permafrost degradation seen in high Arctic terrain

Melting small glaciers could add 10 inches to sea levels


2D materials

Plumbene, graphene's latest cousin, realized on the 'nano water cube'

New flatland material: Physicists obtain quasi-2D gold


humans

What we think we know -- but might not -- pushes us to learn more

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.
