Tools for biomedical research
At the forefront of biomedical research, medical scientists use particle accelerators to explore the structure of biological molecules. They use the energy that charged particles emit when accelerated to nearly the speed of light to create one of the brightest lights on earth, 30 times more powerful than the sun and focused on a pinpoint.

Nanotemplates for nanostructures
Coffee beans spilled upon a table form no pattern—they're a mess—their distribution dictated by the laws of chance. The same was generally believed true of atoms deposited upon a substrate. The first vision of a peaceable kingdom in which deposited atoms form orderly, controllable 2-D nanopatterns has been observed by researchers at the Sandia National Laboratories.

A new addition for weighty research
The latest addition to the Laboratory's collection of FTICR mass spectrometers is the most powerful available commercially. It measures the mass of peptides —small structural units obtained by cutting proteins into pieces — with such sensitivity and precision that scientists can detect hundreds of thousands of peptide species in a single analysis.

Taming the power of power
Joe Oliveira, Janet Jones-Oliveira and a team of engineering experts are taking the first steps toward developing a computer model of the way our country's electrical generating and transmission, distribution and end-user systems operate. This is a daunting challenge because the systems have changed radically in recent years.

On ALERT for energy savings
In early 2001, Pacific Northwest's Michael Kintner-Meyer developed the concept for the program later identified as ALERT—Assessment of Load and Energy Reduction Techniques. His idea was to conduct assessments of federal facilities to identify and implement low-cost or no-cost measures to reduce energy demand and consumption when California's energy system is at its peak, minimizing the potential for blackouts.

New lens could help find cancer tumors earlier
The new lens technology, developed by scientists at Argonne's Advanced Photon Source, uses gamma rays diffracted by a set of 828 copper crystal cubes arranged in 13 concentric rings in a disk slightly smaller than a dinner plate. The lens focuses the gamma radiation emitted from a small radioactive source in the body of a patient into a small, well-shielded detector.

Mysterious material has unusual electrical properties
In the July 27, 2001, issue of Science magazine, the scientists describe findings that offer the first clues to explain the material's newly discovered, unusual electrical properties. This work may lead to applications using the material to store electrical charge in high-performance capacitors, and offer insight into how charges behave on the nanoscale-on the order of billionths of a meter.

New magnetic semiconductor material spins hope for quantum computing
The future of quantum computing offers the potential for substantially greater data storage and faster processing speeds, but its advancement has been limited by the absence of certain critically important materials—in particular, a semiconductor that is magnetic at room temperature. Now, scientists at the Pacific Northwest National Laboratory (PNNL) have created a semiconductor material that has superior magnetic properties at room temperature.

Lab researcher's team shines in protein folding predictions
The protein folding puzzle – determining the3--D structure of a protein given the sequence of its amino acids – is one of the major unsolved problems in molecular biology. A Los Alamos National Laboratory scientist along with a colleague and his students were recently recognized as the most successful team in an annual worldwide assessment of progress in protein structure prediction.

Riding the d-wave
A paper appearing in a recent issue of the journal Nature has helped validate a theory on the enigmatic nature of superconducting materials that was first advanced by Los Alamos National Laboratory researcher Alexander Balatsky and his colleagues five years ago. The confirmation of the theory is another step in solving the enigma of superconductivity.

Lab builds world's first neptunium sphere
For the first time ever, a cross-section of nuclear materials scientists and technicians at the Chemistry and Metallurgy Research (CMR) facility has fashioned an eight- kilogram tungsten-and nickel-clad sphere of neptunium. The actinide metal sphere will be used in criticality safety and nuclear non-proliferation experiments at Technical Area 18, the critical experiments facility.

Building the buckyball -- A bowl at a time
Showing a new, naturally occurring compound to a research chemist is, in a way, like throwing down a gauntlet. The unspoken challenge being issued — create this in the lab. For Peter Rabideau, that gauntlet has been the buckyball. Rabideau, an Ames Laboratory senior chemist, has moved a step closer to meeting that challenge by developing a practical means of producing bowl-shaped segments — buckybowls — that could eventually be pieced together to form the complete ball.

Are the digits of pi random? A Berkeley Lab researcher may hold the key
Pi, the ubiquitous number whose first few digits are 3.14159, is irrational, which means that its digits run on forever (by now they have been calculated to billions of places) and never repeat in a cyclical fashion. Numbers like pi are also thought to be "normal," which means that their digits are random in a certain statistical sense.
