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.

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.

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.

Rapid field detection of biological agents
Livermore scientists have developed two portable biodetection systems to help in the fight against bioterrorism.

Simulating turbulence in magnetic fusion plasmas
Powerful three-dimensional simulations are helping researchers to speed the development of magnetic fusion energy.

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.

1-Jan-2002
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.

EDM cuts cleaner, smoother
The Charmilles Technologies Robofil 290 Wire Electrical Discharge Machine, or EDM for short, uses an electrical spark delivered by a fine wire to cut through any material that conducts electricity.

31-Dec-2001
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.

'Fast-talking' clusters
Researchers at Ames Laboratory's Scalable Computing Lab have extended their investigation into communication technology for cluster computers thanks to a National Science Foundation Major Research Instrument grant awarded to Iowa State University's Center for Physical and Computational Mathematics.

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.

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.

31-Dec-2001
Computer modeling and homeland security
ORNL researchers have developed computer-based products that could provide information to help Americans better protect themselves from natural, accidental, or deliberate threats.

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.

31-Dec-2001
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).

31-Dec-2001
Car crash simulations may improve vehicle efficiency
ORNL researchers are building computer models of vehicles made of aluminum, regular steel, high-strength steel, and carbon-fiber composites. This research could lead to safer, energy-efficient cars.

31-Dec-2001
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.

Chemical experiments and predictions by computer
Supercomputers can be used to simulate chemical reactions, saving time and money and increasing safety.

Retaining and retrieving data more effectively
ORNL is a co-developer of and customer for the computer industry�s leading data-storage system in terms of capacity and transfer speed. The ORNL data-storage program also includes the Probe Storage Research Facility.

Developing computer tools for scientists
ORNL researchers and their university and national lab colleagues are developing tools to enable scientists to run simulation codes more efficiently on massively parallel supercomputers and clusters of personal computers.

The science grid
Science grids are being established to connect scientists, instruments, computing, and data.

View from the top
Lederman Fellow Natalia Kuznetsova describes her research involving the Tevatron, a powerful proton-antiproton collider, and the potential for new, unexpected phenomena that may result from this and other projects at Fermilab.

Just the right type
High school physics teacher and former mechanical engineer Len Bugel is a valuable asset to the Fermilab MiniBooNE experiment, which aims to confirm or refute the evidence for neutrino oscillations claimed by the Liquid Scintillating Neutrino Detector (LSND) experiment at Los Alamos National Laboratory.
