Ramping up the Pressure
Scientists at Lawrence Livermore National Laboratory apply new methods to sort out an old, vexing problem: What happens to minerals under pressure inside Earth and other, more massive planets?
Fission in a Small Package
A device borrowed from particle physics, shrunken down and retooled, is going in at Los Alamos National Laboratory. Experiments on the instrument, a time projection chamber, will add to what we know about fission.
Diamond Soup
The Z machine at Sandia National Laboratories subjects diamond and other matter to extreme heat and pressure, helping validate computer models relevant to nuclear-stockpile security.
