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.

Fermilab and LHC: A major stakeholder
The United States has a $531 million commitment to provide accelerator and detector components for the Large Hadron Collider, which is under construction at CERN, the European Particle Physics Laboratory in Geneva, Switzerland, and which will begin operations later this decade. With a major role in construction of the LHC accelerator and the CMS detector, Fermilab will be positioned for a major role in the emergent physics when LHC begins operating later this decade.

Measuring up
Physics is the science of measurement, and measurement relies on unchanging standards--the inch, the centimeter, the second, the electron volt. But what if a standard is distorted and unreliable? How can a measurement be accurate?

Notes from underground
Neutrinos fly through the earth with the greatest of ease. In the blink of eye, they flit effortlessly through the planet's rocky crust at nearly the speed of light. Not so for the miners of generations past who dug their way, foot by backbreaking, dangerous foot, through the rock of Minnesota's Iron Range.

Tiny device can detect hidden nuclear weapons
A small, portable detector for finding concealed nuclear weapons and materials has been developed by the Argonne National Laboratory. When fully developed, the device could assist international inspectors charged with preventing smuggling and unauthorized use of nuclear weapons and materials.

Air quality study focuses on New England
In an effort to identify why the Northeastern US has some of the worst air quality in the country, NOAA's largest research vessel, along with the Department of Energy's Gulfstream research aircraft, will monitor air pollutants and their transport in the region this summer.

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.

Wallace recognized for work in China
NREL's Bill Wallace was awarded the 2001 Chinese National Friendship Award for his outstanding contributions towards the long-term development of renewable energy in China. The Friendship Award is the highest-level state award that can be given to foreign experts in China. In 2001, 50 foreign experts from 17 countries were recognized in ceremonies conducted during the national celebration of the 52nd anniversary of the founding of the People's Republic of China.

NREL sponsors Habitat House in honor of anniversary
The Department of Energy's National Renewable Energy Laboratory's managing partners, Midwest Research Institute (MRI), Battelle and Bechtel, are sponsoring the construction of a Habitat for Humanity home by providing the sponsorship fee. NREL's commitment calls for 3,000 volunteer hours to help build the house. Volunteers will be recruited from NREL and DOE staff, friends and family members.

More clues about obesity revealed by brain-imaging study
The idea that obese people eat too much because they find food more palatable than lean people do has gained support from a new brain-imaging study at the U.S. Department of Energy's Brookhaven National Laboratory. The study reveals that the parts of the brain responsible for sensation in the mouth, lips, and tongue are more active in obese people than in normal-weight control subjects.

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.

Particle physics made painless
When you're searching for something, you can usually count on finding it in the last place you look. The search might take you through countless nooks and crannies, but each one that comes up empty serves to reduce the number of nooks and crannies remaining to look.

Come-from-behind success
Research can be as dramatic as a sports tournament. Even if you are off to a slow start, your team still can show a strong performance in the playoffs. The discovery of the bottom quark, found twenty-five years ago at Fermilab, is a case in point.

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.

Have doubly-charmed baryons been discovered?
On May 31, 2002, a group of physicists presented the results of a year-long analysis of an experiment carried out at the Department of Energy's Fermi National Accelerator Laboratory. Sifting through the data of particle collisions in which they produced particles made of three quarks, the experimenters found signals that indicate the creation of new particles with quark combinations never observed before. However, experimenters emphasized that significant questions remain in the interpretation of these results.

A deep sense of place
If Gertrude Stein had ever visited this far northeastern corner of Minnesota, she probably would have written about the Soudan region in the same way she did about Oakland, California: "There is no there, there" But that's all right, because the people up here like it that way. And they'd know that Gertrude Stein never worked in a mine. Most people up here have, one time or another, often through more than one generation, and often through lean times.
