Argonne Scientists Create New Oil-resistant Filter Technology
Crude oil is sticky stuff and often clogs filters membranes and other equipment used in the oil and gas industry. To address this problem, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed a novel approach, which will prolong the lifetime of key industrial equipment.

Learning Continues Throughout Summer for ALCF Student Interns
Every summer, the halls of Theory and Computing Sciences Building at the U.S. Department of Energy’s (DOE) Argonne National Laboratory are a little noisier. This year, the ALCF interns ranging from undergraduates to Ph.D. candidates came from all over the country to gain hands-on experience with some of the most powerful supercomputers in the world.

Seeing a Salt Solution's Structure Supports One Hypothesis About How Minerals Form
Scientists at the Department of Energy’s Oak Ridge National Laboratory used neutrons, isotopes and simulations to “see” the atomic structure of a saturated solution and found evidence supporting one of two competing hypotheses about how ions come together to form minerals.

Scientists Present Ideas for Next-gen Accelerator Experiments
With powerful beams of electrons 100 to 1,000 times brighter than its predecessor, the upgrade to the Facility for Advanced Accelerator Experimental Tests (FACET) promises technological breakthroughs that could lead to a new generation of smaller, more affordable particle accelerators for research in particle physics, X-ray science, medicine and other fields.

Celebrating the 60th Anniversary of Technetium-99m
The tracer, technetium-99m (Tc-99m), is the radioactive isotope responsible for 80 percent of the nuclear medical imaging procedures performed in the world. Though the element technetium was discovered in the 1930s, it wasn’t readily available for imaging procedures until three Brookhaven researchers—Walt Tucker, Powell “Jim” Richards, and Margaret Greene—developed a way to generate the isotope on the spot in hospitals.

Researchers Switch Material from One State to Another with a Single Flash of Light
Scientists from the Department of Energy’s SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, and then back again, with single flashes of laser light.

Spotlighting Differences in Closely-Related Species
There are millions of fungal species, and those few hundred found in the Aspergillus genus play important roles in areas ranging from industrial production to agricultural plant pathogens. A team led by scientists at the Technical University of Denmark, the U.S. Department of Energy (DOE) Joint Genome Institute (JGI), a DOE Office of Science User Facility, and the Joint Bioenergy Institute (JBEI), a DOE Bioenergy Research Center, present the first large analysis of an Aspergillus fungal subgroup, section Nigri.

Surprise Finding: Discovering a Previously Unknown Role for a Source of Magnetic Fields
Magnetic forces ripple throughout the universe, from the fields surrounding planets to the gasses filling galaxies, and can be launched by a phenomenon called the Biermann battery effect. Now scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that this phenomenon may not only generate magnetic fields, but can sever them to trigger magnetic reconnection – a remarkable and surprising discovery.

STAR Detector on the Move
How long does it take to roll a twelve-hundred-ton detector one hundred feet? In late August, it took 10 hours for the STAR detector to roll from its regular spot in the interaction region of the Relativistic Heavy Ion Collider (RHIC) to the assembly building to undergo maintenance. It’s all part of a program to keep this giant multi-purpose particle detector (kind of like a giant 3D digital camera) in tip-top condition for capturing subatomic smashups at RHIC, a DOE Office of Science user facility for nuclear physics research at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory.
