The Neutron Express
A ride around toy train tracks inside an experimental fusion machine can reveal much about a hot gas called plasma. Research staff at DOE's Princeton Plasma Physics Laboratory recently mounted a neutron source on a toy train inside the National Spherical Torus Experiment (NSTX), placed it on hobby train tracks that had been installed and sent it on a three-day continuous zip around the rails. -
LANL fires a DAHRT
After decades of work, scientists and engineers at DOE's Los Alamos National Laboratory have fired the first-ever double-viewpoint hydrodynamic test of a nuclear weapon mockup. The test took place on December 3, 2009 at the Dual Axis Radiographic Hydrodynamic Test (DARHT) facility at Los Alamos.

NETL Researchers Develop Promising New Photocatalyst for CO2 Reuse
Researchers at the National Energy Technology Laboratory have developed a new, heterostructured photocatalyst capable of using the low-energy, visible-light portion of the electromagnetic spectrum for converting CO2 and H2O into methane, methanol, and other value-added chemicals. In this system, CdSe nanocrystals absorb visible light photons, creating excited electrons which are injected into TiO2 to reduce CO2. -
A speedy CAT scan for cells
A team from DOE’s Lawrence Berkeley National Laboratory, Stanford University, and the University of California at Berkeley have used the National Center for X-ray Tomography at Berkeley Lab’s Advanced Light Source (ALS) to make 3-D movies of the internal structure of Candida albicans, a microbe that can cause yeast infections, capturing the changes that occur when the organism is exposed to a new and promising antifungal therapy. -
Ge Mini: Portable gamma spectrometer
A team of scientists and engineers from DOE's Lawrence Livermore National Laboratory has developed GeMini--a portable gamma-ray spectrometer based on germanium technology. The instrument is so small that it fits in the palm of a hand, and this spectrometer is outfitted with an innovative low-powered, miniature cooling mechanism.
