Researchers reach to the skies to reveal the secrets of the stars
In 2003, Argonne scientists will analyze solar wind--single atoms and electrically charged particles from the sun--samples from NASA's Genesis mission in an effort to better understand how the planets formed and how the sun works. If successful, Genesis will become the first mission to return a sample of extraterrestrial material from beyond the moon. These samples will allow a precise measure of the elemental and isotopic composition of our most important star - the sun.

Disorderly superconductors caught in the act
The "granular" nature of superconductivity in underdoped high-temperature superconductors proposed by theorists has had some believers but many skeptics. New observations, reported in the 24 January issue of Nature, may shift how researchers think about these materials.

Neutrino measurement surprises Fermilab physicists
Experimenters at Fermilab's NuTeV (Neutrinos at the Tevatron) experiment measured the ratio of two types of particles—neutrinos and muons—emerging from high-energy collisions of neutrinos with target nuclei.

Microarrays for detecting pathogens
Microarrays are tiny probes placed on a piece of glass or other material. Each probe is sensitive to a specific pathogen. The arrays are flooded with a complex mixture of DNA or RNA from environmental samples and individual probes react if particular pathogens are present.

Fermilab 2002: The outlook
If we learned anything from the year 2001, it is the impossibility of predicting what the next twelve months will bring. Nevertheless, at least one thing seems certain: 2002 at Fermilab will see unique scientific opportunities and extraordinary challenges for physics at the energy frontier.

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.

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.

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.

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.
