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 acoustic camera captures picture of fish passage
If a picture is worth a thousand words, then how valuable is a high-resolution image of fish seen through murky water? Very valuable, according to scientists seeking to understand fish movement near hydropower dams. Recently, fisheries biologists at Pacific Northwest National Laboratory deployed an acoustic camera originally designed for the Navy at a dam in the Northwest to study and illuminate their understanding of fish behavior.

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.

The magnetic universe
Researchers in Applied Physics and Theory Divisions have recently compiled a sample of nearly 100 giant radio galaxies powered by black holes.

Researchers find human's earliest ancestor yet
An international team of researchers has announced the discovery of fossil bones and teeth belonging to the earliest human ancestors yet discovered � a hominid who lived in what is now Ethiopia between 5.2 and 5.8 million years ago.

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.

Earliest hominid discovery not the missing link � But close
The discovery of fossil remains of a hominid that lived in what is now Ethiopia between 5.2 and 5.8 million years ago are the subject of two articles in the July 12 issue of Nature. Hominid refers to the family of primates that includes all species on the "human" side of the evolutionary tree after the split from chimpanzees.

Radiation treatment in ducks may offer clues to brain tumors in children
The Department of Energy's Brookhaven National Laboratory has tested an experimental microbeam radiation therapy on duck embryos that may offer clues about how to treat brain tumors in infants and young children.

The great solar car race: Cars will race along Route 66 without a drop of gas
As many as 40 race cars will leave Chicago July 15 in the first-ever attempt to travel America's historic Route 66 without spending a penny on gasoline. In a year that has seen unpredictable energy and gasoline prices, these drivers are betting that sunshine will take them all the way to Los Angeles, a feat that has never been tried in the 75-year history of the highway.
