Granular flow dynamics and collapse mechanisms represent a rapidly evolving area of research that spans fundamental physics, geotechnical engineering and natural hazard assessment. At its core, the ...

When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very ...

Shear transmission in granular flow is intrinsic to systems ranging from geophysical flows to industrial processing, and peculiarities in granular shear response have consequences that can be dramatic ...

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 ...

There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science ...
