A clear view
It is as translucent as glass. It comes by train, two railcars every week. Fermilab will receive 250,000 gallons of it, enough to fill a 25-meter swimming pool. What is it? Some of the clearest mineral oil available in the country, intended for the MiniBooNE experiment.

Sandia 'detective' solves strange case
It was a small problem: a layer of water lying flat instead of slightly bumpy as it froze on a solid. It became a larger problem when no one could explain why that might happen. The slight difference between experimental results and established expectations might have meant nothing. But possibly it was signaling a basic scientific misunderstanding concerning the interaction of water with solids -- an area of major industrial and scientific concern.

New magnetic refrigerator
Using materials developed at the U.S. Department of Energy's Ames Laboratory, researchers have successfully demonstrated the world's first room temperature, permanent-magnet, magnetic refrigerator. The refrigerator was developed by Milwaukee-based Astronautics Corporation of America as part of a cooperative research and development agreement with Ames Laboratory.

Molecular structure of cancer-related proteins identified
Scientists have identified the biochemical and signaling properties of two cancer-related proteins using a process called X-ray crystallography. The technique yielded the first-ever detailed pictures of the proteins interacting with each other, indicating which areas are most essential for the development of cancer.

Present at the Creation
When they synthesized elements 114 and 116, Russian and Livermore scientists confirmed decades-old predictions of the existence of superheavy elements with comparatively long lifetimes.

Creating a robot colony
Scientists at the Idaho National Engineering and Environmental Laboratory are creating an army of small robots--a fleet of inexpensive mini-robots designed to work harmoniously to perform tasks too hazardous or just downright boring for humans. Simple biological societies, such as ant colonies and beehives, serve as handy models for creating large groups of small, disposable robots.

BAM continues amazing development
A material that rivals industrial diamond in hardness continues to amaze the researchers who developed it and attract interest from a variety of industrial sectors. The material represents a breakthrough technology that could have a substantial impact on the machining industry, which spends $300 billion each year in labor and overhead in the United States alone.

Building on success
When researchers at Ames Laboratory developed a compact laboratory furnace, it marked a huge leap forward in the ability to understand what happens to a material's crystal structure as the material is heated and cooled. That success has led to the building of two additional furnaces for other DOE laboratories and a refined design intended to make the furnace easier to operate.

Biothreat detection takes concentration
Detecting potential biological threats is part of the Department of Energy's plan for homeland defense, and a new automated device developed by Pacific Northwest National Laboratory provides a key piece in biothreat detection technology.

Spectrometers — versatile tools for weapons detection
Pacific Northwest National Laboratory is using four kinds of spectroscopies to develop sensors that can be used to detect weapons of mass destruction: mass spectroscopy, Raman spectroscopy, neutron spectro-scopy and optical spectroscopy.

A partner in peace
At Pacific Northwest National Laboratory, however, many researchers are working on programs aimed at keeping people safe and the world at peace. We asked Mike Kluse, Associate Laboratory Director for Pacific Northwest's National Security Directorate, about the Laboratory's role as a partner in peace and what has changed since the tragic events of Sept. 11.

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).
