Biology research goes in silico
Long before a new jumbo jet takes off the runway, all of its systems and subsystems down to the tiniest of individual parts have been virtually designed, built and tested through the use of computer models and simulations. Similarly, Pacific Northwest National Laboratory is developing virtual cells that can be explored, tested and manipulated within the world of computers to make important discoveries in systems biology.

Imaging system visualizes plasma turbulence
Researchers from three laboratories funded by the U. S. Department of Energy have captured high-resolution images of instabilities that cause heat to leak rapidly from the plasma edge of the National Spherical Torus Experiment (NSTX) and the Alcator C-Mod fusion experiments. Advanced imaging cameras were used to freeze plasma action at a rate of up to 1 million frames per second.

Ames Laboratory puts the 'squeeze' on communications technology
A new message-passing library that makes it possible to extract optimum performance from both workstation and personal computer clusters, as well as from large massively parallel supercomputers has been developed by researchers at Ames Laboratory. The new library, called MP_Lite, supports and enhances the basic capabilities that most software programs require to communicate between computers.

Biosig finds new meaning in microscope images
A team of computer scientists working with cell biologists at Lawrence Berkeley National Laboratory has created BioSig, a web-based bioinformatic system that links collections of microscope images to a wide variety of quantitative experimental data. The new program can be used by multiple researchers to answer questions and test hypotheses about protein expression, cell morphology, and cellular organization in tissues and cell cultures.

Conducting-insulating materials reveal their secrets
Research by physicists at the U.S. Department of Energy's Brookhaven National Laboratory provides new insight into why some materials made of stacks of metallic planes are conductors in the direction of the planes and are insulators in the direction perpendicular to the planes. Such behavior is in marked contradiction with scientists' traditional understanding of metallic conductivity, where the electrical current is carried by electrons in every direction.

Angling for a better (nano) surface
A promising method for creating and studying chemically tailored nanocrystalline surface materials was recently developed by researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory. Results are reported in the April 11, 2002, issue of the Journal of Physical Chemistry B.

Forensic science center maximizes the tiniest clue
Lawrence Livermore's Forensic Science Center combination of human and technological resources has made it among the best of its kind for collecting and analyzing virtually any kind of evidence, some of it no larger than a few billionths of a gram. Its resources, expertise, tools, and techniques are applied to all kinds of cases, from the September 11 World Trade Center attack to the spread of anthrax spores, from multiple homicides to nuclear materials smuggling.

Mapping the microbial world
Scientists are cataloguing and mapping the life inside Yellowstone’s hot pools. Hardy microorganisms ranging from emerald-green bacteria to fire-red rock slime have long fascinated microbiologists with their ability to live in the scalding hot water at Yellowstone National Park, the acidic ore deposits of abandoned mines or the salt pools of the Great Salt Lake.

Near-frictionless carbon coating nears commercial applications
Four years and more than 3,000 phone calls and e-mail contacts later, Argonne's "near-frictionless carbon" coating stands on the brink of commercialization. A sample of the coating on a sapphire substrate survived 17.5 million passes of a steel ball. After 32 days, the testing machine failed, but the ball left only a barely visible track on the coating.

Molecular shuttling
The Department of Energy's Sandia National Laboratory researchers observed molecular shuttling on a man-made membrane that mimics cellular behavior. Recurring movements may evolve into rudimentary tools of nanoconstruction. These observations were published as the cover story in the April 30, 2002, issue of the chemical and biophysics journal Langmuir.

Simulating supernovae on supercomputers
Multidimensional simulations of core-collapse supernovae will answer important questions about the creation and dissemination of elements that make life possible. They may also be important in the development of “enabling technologies” for other applications, such as combustion, climate, fusion, stockpile stewardship, and nuclear medicine.
