7-Jan-2002
Molecular structure of cancer-related proteins identified Scientists have identified the biochemical and signaling properties of two cancer-related proteins using a process called X-ray crystallography. The technique yielded the first-ever detailed pictures of the proteins interacting with each other, indicating which areas are most essential for the development of cancer. Contact: Karen McNulty Walsh

Idaho Accelerator Center leads the way in research and education The Idaho Accelerator Center stands as a monument to the future--using science to develop devices to further national security, healthcare, and business. Contact: James Jones
22-Oct-2001
Cancer-detecting microchip clever technique for detecting proteins by inducing them to stick to and bend a microscopic cantilever—essentially a diving board the size of a hair—is sensitive enough to serve as a diagnostic assay for the protein markers characteristic of prostate cancer, a team of scientists report in the September issue of the journal Nature Biotechnology. Contact: Robert Sanders
15-Oct-2001
Spinach protein could offer new hope for the blind Spinach, touted in the Popeye cartoon for its ability to strengthen the body, may prove even more valuable for restoring vision to people who are legally blind. People who suffer from age-related macular degeneration or retinitis pigmentosa, diseases that are leading causes of blindness worldwide, may find hope in this research. Contact: Ron Walli

How some viruses take strong hold of cells As part of an ongoing effort to understand how viruses infect cells, scientists at DOE's Brookhaven National Laboratory have deciphered the molecular-level interaction between coxsackievirus—which infects the heart, brain, pancreas, and other organs—and the human cell protein to which it attaches. This work may lead to improved ways to thwart viral infections, and may help scientists design virus-based vehicles for gene therapy. Contact: Karen McNulty Walsh

Taking the heat off: Nanofluids promise efficient heat transfer By manipulating atoms on the smallest of scales, Argonne scientists have created a next-generation fluid that may revolutionize heat transfer. By adding tiny spherical particles to a conventional fluid, researchers can improve by up to 40 percent its ability to transfer heat. Contact: Evelyn Brown
1-Oct-2001
Travels of a young physicist A young physicist recounts his career from the University of California at Berkeley and the laboratories of Alexander Pines, famed pioneer in nuclear magnetic resonance (NMR) to the Scuola Normale Superiore in Pisa, Italy. Contact: Ron Kolb

Tools for healing Discoveries in physics have helped forge dramatic advances in cancer treatment for over a century. In 1950-54, according to the National Cancer Institute, the five-year survival rate for all cancers was 35 percent; by 2000 it was 59 percent. With early detection and treatment, the five-year survival rate for screenable cancers is now 80 percent. Contact: Judy Jackson
14-Sep-2001
Tools for the future The future of accelerator physics isn't just for physicists. As in the past, tomorrow's discoveries in particle accelerator science may lead to unexpected applications for medical diagnosis, healing and the understanding of human biology. Contact: Judy Jackson

Neutrons against cancer The idea to build a Neutron Therapy Facility at Fermilab developed in the early 1970s when physicians and physicists shared a vision: to wield accelerator technology to combat cancer. Today, more than 3,100 patients have come to Fermilab in the hope of finding a cure for some of the worst tumors known in the medical field. Contact: Judy Jackson

Tools for diagnosis Advances in technology for medical diagnosis have created extraordinary new capabilities for imaging the human body. Many of medicine's most powerful diagnostic tools incorporate technology that physicists originally developed to explore the fundamental nature of matter. Contact: Judy Jackson
14-Sep-2001
Interdependent sciences: Physics and medicine Many diagnostic and therapeutic techniques that have revolutionized medicine are also symbols of the interdependence of the physical and biomedical sciences. Magnetic Resonance Imaging and Neutron Therapy are just two of the prominent examples of the successful collaboration among innovative medical researchers, physical scientists and engineers.
