The Song of the Dunes Deciphered

Desert sand dunes, blown by merciless desert winds, have been known to “sing”, often loud enough to be heard for miles. New research of dunes in Morocco and Oman has figured out why it happens.

It’s not a trapped genie, unfortunately. But the reason might be just as cool. Similarly-sized grains of sand, blown by a wind of pretty steady velocity, create sound waves thanks to small avalanches of these almost identical sand grains.

Peacefully haunting sound, and some pretty cool science to go along with it.
