Drops of water striking a bed of grains can leave a wide range of crater shapes and sometimes a bigger impression at low and high impact speeds than at medium speeds. The work may help geoscientists identify ancient formations.

The turbulent atmosphere is better than an equivalent glass fiber when it comes to preserving quantum information in long-distance light signals, according to a new analysis. For brief moments, light can propagate relatively undisturbed.
