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 ...

Sand in an hourglass might seem simple and straightforward, but such granular materials are actually tricky to model. From far away, flowing sand resembles a liquid, streaming down the center of an ...

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 ...

CAMBRIDGE, Mass. -- Sand in an hourglass might seem simple and straightforward, but such granular materials are actually tricky to model. From far away, flowing sand resembles a liquid, streaming down ...

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 looks like ordinary sand, rocks or snow flowing in one direction can actually hide swirling currents that move in multiple directions beneath the surface. Subscribe to our newsletter for the ...

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.
