Brrr! Winter still has much of the country in its iron grip. While you're waiting for spring to make its presence known, perhaps you'd like to try your hand at photographing Snowflakes in Freefall. A team of researchers at the University of Utah have developed a Multi-Angle Snowflake Camera to do just that. Related: here are 5 Of The Coldest Places Where Science Is Happening.

The Ancient Physics Quest of ‘Perfect Packing’ Has a New Solution. "If you walk on sand, it supports your weight,” write a team of Duke researchers in a new study. “How do the disordered forces between particles in sand organize, to keep you from sinking? This simple question is surprisingly difficult to answer experimentally: measuring forces in three dimensions, between deeply buried grains, is challenging."
