This polarized light image shows ice grains deformed in experiments with the ring-shear device in Neal Iverson's Iowa State laboratory. The experiments show that grains, on average, grow about 3 times ...

Ordered magnetic fields spontaneously emerge out of chaotic, tangled fields. This finding is consistent with astrophysical observations. Streamlines of magnetic fields are 3D-rendered and are colored ...

Laboratory experiments designed to deform ice at its pressure-melting temperature were like grabbing a bagel at the top and the bottom, then twisting the two halves to smear the cream cheese in the ...
