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 ...

Neal Iverson started with two lessons in ice physics when asked to describe a research paper about glacier ice flow that has just been published in the journal Science. First, said the distinguished ...

In January I wrote a piece titled “5 Physics Equations Everyone Should Know.” Lots of you weighed in with your own nominations, and there were plenty of good suggestions. So I’ve decided to do a ...

Melting Arctic ice is revealing a hidden ecosystem where bacteria convert nitrogen gas into nutrients, fueling algae growth. This process, previously thought impossible under thick ice, is now seen as ...

AMES, Iowa – Neal Iverson started with two lessons in ice physics when asked to describe a research paper about glacier ice flow that has just been published by the journal Science. First, said the ...

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 ...
