EDITORIAL

All for one, one for all I have attended a large number of trade shows in several different industries over the years and, while I know generally what to expect, I am often pleasantly surprised by what I find. I never get tired of seeing an industry in action in what could be described as a mash-up of sales call, summer school and family reunion, carried out in the spirit of “all for one and one for all.”...

Nanoscale 3-D images shed light on Earth’s core

Physicists can study the Earth’s inner history, thanks to a technique that provides a picture of minerals interacting at ultrahigh temperatures and pressures. The new method, high-pressure nanoscale x-ray computed tomography, is being developed at SLAC National Accelerator Laboratory and has enabled Wendy Mao, a mineral physicist at Stanford University, to look at the separation of...
