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. Contact: Catherine Foster

R & D 100 Award is fourth for Ed Yeung and 15th for Ames Lab Ed Yeung, program director of Chemical and Biological Sciences, has won a 2001 R&D 100 Award for a remarkable advance in chemical separation technology called multiplexed capillary electrophoresis using absorption detection. Contact: Steve Karsjen
11-Jul-2001
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. Contact: Karen McNulty Walsh
1-Jul-2001
More than the bare bones for implant patients At Pacific Northwest National Laboratory, researchers developed a unique bone-like coating process that addresses the problem of poor bonds between artificial joints and real bone. It could potentially increase the useful life of hip, knee and other joint replacements as well as dental implants. Contact: Greg Koller
1-Jul-2001
Drug delivery right on target One of the challenges in treating cancerous tumors with chemotherapy and medical isotopes is maximizing the treatment of cancer cells while minimizing the potential for harming healthy tissue. With materials being developed at Pacific Northwest National Laboratory, however, a more targeted approach might be on the way. Contact: Greg Koller
1-Jul-2001
Radiation bystander effects An important discovery about the effects of low-level radiation on cells is altering long-held beliefs about risk assessment in radiation exposure. Contact: Bruce Lehnert
19-Jun-2001
Disease detectives ORNL researchers are developing two types of miniaturized devices for diagnosing diseases. These devices are based on cantilevers and biochips. Contact: Billy Stair
19-Jun-2001
A model fish for pollutant studies The zebrafish is a model organism for studying the effects of endocrine-disrupting chemicals on gene and protein expression. Contact: Billy Stair
19-Jun-2001
SNS and biological research Three world-class biological instruments are being designed for the Spallation Neutron Source. They will help biologists determine the atomic-level structure of proteins and other signaling compounds that allow cells to communicate and coordinate activities across an organism. The research could lead to safer, more effective drugs. Contact: Billy Stair
19-Jun-2001
Lab on a chip used for protein studies ORNL's lab on a chip is being used commercially to identify proteins and shows promise for drug discovery and disease screening. Contact: Billy Stair
14-Jun-2001
New findings on breast cancer reported at the annual AAAS meeting New experimental findings by the Lawrence Berkeley National Laboratory (Berkeley Lab) cell biologist Mary Helen Barcellos-Hoff show that exposure to ionizing radiation creates a microenvironment in the tissue surrounding breast cells that can cause even nonirradiated cells and their progeny to become cancerous. The discovery suggests new and possibly more effective means for preventing breast cancer. Contact: Lynn Yarris
1-Jun-2001
Stable isotope research resource The ability to apply research techniques to important problems in biology and medicine depends on the availability of isotopically labeled compounds. Contact: Clifford Unkefer
1-Jun-2001
Early detection for protection Being able to rapidly detect biological agents is among the most difficult and yet urgent tasks facing the nation. Whether the threat is from a natural outbreak or a terrorist's release of threat agents, medical treatment cannot effectively begin without first identifying the bioagent. At the same time, effective understanding and response to a biological threat requires rapid communication across the health-care system. Contact: Paul Jackson
1-Jun-2001
Using pathogen sequence data As scientists delve into the vast quantity of biological data currently being produced, the problems of handling such a treasure trove of information are daunting. New tools and techniques for managing, storing, analyzing, mining and visualizing this information are the focus of much attention in the scientific community, especially when the data can have a bearing on public health and even emergency response. Contact: Paul Jackson
1-Jun-2001
Unraveling anthrax Los Alamos National Laboratory's Bioscience Division researchers have developed technologies that can uniquely identify the origins of biological organisms based on information in the DNA. Contact: Paul Jackson
1-Jun-2001
Rapid Syndrome Validation Project Los Alamos National Laboratory is collaborating on a new tool that will provide public health officials with an early warning and response system for threats to public health. Contact: Sandra Zink
1-Jun-2001
Optical biopsy studied as breast cancer treatment aid Breast cancer is the leading cause of cancer-related death in women aged 40-59 and was expected to total more than 45,000 deaths in the United States last year, according to the American Cancer Society. A Los Alamos National Laboratory-developed technology, the Optical Biopsy System (OBS), may aid in not only the diagnosis of breast cancer, but the success of the surgical treatment as well. Contact: Judith Mourant

Unmasking the mysteries of chronic beryllium disease Beryllium is a unique lightweight metal used in nuclear weapons and, in the commercial sector, for telescope mirrors, golf clubs and a variety of other applications. While solid beryllium and beryllium alloys are safe, fine particulate beryllium is hazardous if inhaled. Contact: Babetta Marrone
1-Jun-2001
'SNP'ing' away at human health issues In the summer of 2000, scientists around the world cheered as the effort to unravel the mystery of the human genome reached a milestone—a completed draft of the human genome sequence. The sequence is a set of instructions that determines individual characteristics ranging from the cosmetic, such as hair and eye color, to the medically important, such as susceptibility to disease and response to treatments. Contact: Scott White
1-Feb-2001
Separation technology unites lab, new company One of Ed Yeung's latest developments — multiplexed capillary electrophoresis using absorption detection — is an innovation that marks the first time that Yeung has been directly involved in launching a new company based on his technology.
