How to build a stronger neutrino detector
Scientists at DOE’s Brookhaven National Laboratory working on the proposed Long Baseline Neutrino Experiment (LBNE) have set up a death trap for the key components of the project’s future neutrino catchers.

Top quarks may provide clue to new asymmetry
The CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory has found signs of a surprising asymmetry in the production of heavy, elementary particles known as top quarks.

No longer pining for organic molecules to make particles in the air
The fresh scent of pine has helped scientists find missing sources of organic molecules in the air — which, it could well turn out, aren’t missing after all. Scientists at DOE’s Pacific Northwest National Laboratory and Imre Consulting discovered the particles, known as secondary organic aerosols (SOA), aren’t liquid droplets. Instead, these particles are solid and evaporate more than 100 times slower than expected, never equilibrating with their surroundings.

Synchrotron X-rays shine a light on the reactivity of water-gas shift catalysts
In order to better understand how water-gas shift (WGS) catalysts convert carbon monoxide and water from gasified coal into electrical power and valuable fuels, researchers at DOE’s National Energy Technology Laboratory have turned to synchrotron-based x-ray techniques.
