Ice on a Deadline: More Stress Makes Ice Move Faster
Anyone seeing photographs of glacier and ice sheets from above clearly sees that they flow; recent laboratory tests on ice further reveal the conditions that control just how fast this happens.

A Dipole Field from the Ediacaran-Cambrian Transition Onward?
The Ediacaran features an instable magnetic field complicating paleogeographic reconstructions; a new paleointensity study on late Ediacaran rocks indicates a weak but stable dipolar field.

Coupled Mechanisms of Fluid Transport Across the Crust
Magmatic fluid moves up in the ductile zone through porosity waves, accumulates in high-porosity lenses, and migrates across the brittle zone in a convection pattern involving also meteoric fluid.

New Inversion Method Improves Earthquake Source Imaging
A new method uses Bayesian inference to jointly invert for non-planar fault geometry and spatially variable slip (with associated uncertainties) in earthquake source modeling, based on geodetic data.
