From the stone age to the lego block age of computing
The Center for Component Technology for Terascale Simulation Software (CCTTSS), another of ORNL's projects to receive funding from DOE's Scientific Discovery through Advanced Computing (SciDAC) Program, may well revolutionize the way terascale software simulations are developed.

Dirty coal, clean power
Iver Anderson thinks the solution to the rolling power blackouts in California and parts of the East Coast may lie under the rolling black soil of Iowa’s farm country. "Iowa is sitting on top of huge deposits of coal," says Anderson, an Ames Laboratory senior metallurgist. "The problem is that it’s high-sulfur, dirty coal." Anderson and colleagues Bob Terspstra and Brian Gleeson are closing in on a new material to filter the nasty ashes and dust that result from burning "dirty" coal.

Molecular roller coaster analyzes compounds
Visualize a pack of various molecules in a compound, all mingling in a solution. Then imagine molecules being whisked away from the crowd, one at a time, into a tiny tube by an invisible force. About halfway through this molecular roller coaster, the molecules are flashed with ultraviolet light beamed through a small window as they scream by. That, in short, describes the operation of a new instrument created by Ed Yeung and his team of researchers at the Ames Laboratory.

Old material makes a new debut
Magnesium diboride is a relatively inexpensive metal compound that can be purchased in powder form from most standard chemical supply companies. Until this year, there was nothing remarkable about it — at least nothing that was known. But the material had never been investigated for superconductivity — whether it had the ability to conduct electricity perfectly, without resistance, when cooled to temperatures near absolute zero (minus 459 degrees Fahrenheit).

Computer modeling aids understanding of plasma physics
ORNL fusion researchers are using supercomputers to understand plasma turbulence, design a device that could eliminate plasma disruptions, and find ways to get radio waves to not only heat but also control the plasma to allow sustained energy-producing fusion reactions.

New way to make 'neuts'
Neutrons can penetrate deeply to find defects in large machine parts or tiny microdevices, elucidate the structure of biological systems and polymers, sense fluids in geological formations, and probe solids and liquids on the atomic scale.

Laser-induced breakdown spectroscopy measures carbon in soils in a flash
With increasing international concern about greenhouse gases and global warming, scientists have sought better and more cost-effective approaches for measuring changes in the amount of land-based carbon, much of which is located in soils. But because the amount of carbon varies considerably from one spot to the next, measuring significant changes in land-based carbon in fields, ranch lands and forests is difficult.

Afterglows, the hard way
Combining the newest of astronomical instruments with the most venerable techniques of patient attention to detail, scientists at the Department of Energy's Fermi National Accelerator Laboratory, the University of Chicago and other institutions believe they have made the first optical observation of a gamma ray burst afterglow unprompted by prior observation of the gamma ray burst itself-a so-called "orphan afterglow."

NSF grant triggers wide computing possiblities form BTeV
Everybody talks about crashing computers, but nobody does anything about them. But with a $4.98 million National Science Foundation grant in the area of Information Technology Research, Fermilab's B-physics at the Tevatron experiment (BTeV) just might help solve the puzzle of "Why don't things always work as well as we'd like?"

A new way to visualize cells and nuclei
To learn how tissues develop and maintain their organization—and especially to learn what goes wrong when cancer strikes—it's essential to study individual cells and their nuclei within tissues. The problem is that in real tissues, and in many cell cultures grown in the laboratory, cells are often tightly clustered; their boundaries and the borders of their nuclei are hard to distinguish.
