(PhysOrg.com) -- In more than 30 locations around the world, the phenomenon of singing sand dunes has intrigued explorers, tourists, and scientists. When an avalanche occurs or even when the sand is pushed by hand, it emits ...
Saturn's moon Titan looks very much like Earth from space, with rivers, lakes, and seas filled by rain tumbling through a thick atmosphere. While these landscapes may look familiar, they are composed of materials that are ...

(PhysOrg.com) -- The sandfish lizard (Scincus scincus) lives in the desert sands of North Africa and burrows through the sand by wriggling. Now scientists in the US have created a computer model that emulates the physics ...
(PhysOrg.com) -- Titan's vast dune fields, which may act like weather vanes to determine general wind direction on Saturn's biggest moon, have been mapped by scientists who compiled four years of radar data collected by the ...
