If you went to Mars and took a closer look at some of the planet’s steepest slopes, then you would probably come across surface features known as recurrent slope lineae (or RSL for short). Image ...

Take two panes of glass and glue them together with liquid and sand in between, and you’ve got the makings of some eye-popping dynamic sandscape art. For the above video, Joey Shanks (Shanks FX, in ...

Dark features on Mars previously considered evidence for subsurface flowing of water are interpreted by new research as granular flows, where grains of sand and dust slip downhill to make dark streaks ...

British poet William Blake once wrote that a world was contained in a grain of sand. Physicists have done one better, finding a surprising link between streams of flowing sand grains and the birth of ...

What if sand flowed like water? Researchers have just demonstrated that even without an attractive force between grains in flowing sand, they have a cohesion similar to that of liquids. What if sand ...

Dark surface features previously considered evidence of subsurface water flow on Mars have now been interpreted as being the result of dry, granular flows according to a new Nature Geoscience paper.
