While breast cancer screening in rural America remains underutilized, barriers to screening mammography in poor, rural areas are marked by significant racial disparities, according to a new study. These barriers include poor knowledge about breast cancer and screening, difficulty accessing facilities, and lack of encouragement and funds to get screened. These factors are particularly striking among Native Americans. The study will be published in the December 1, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of this study will be available via the CANCER News Room upon online publication.
Recent advances in breast cancer screening and treatments have led to an important reduction in death rates from breast cancer in American women in recent years. While early detection has been shown to reduce breast cancer deaths, its impact on mortality rates across the nation depends on large numbers of women getting screened. Current screening rates approaches 40 percent of eligible women, far less than the national goal of 80 percent. Women in rural America, particularly from minority groups, have even lower utilization rates.
In 1996 an intervention designed to increase screening among low-income women called the Robeson County Outreach Screening and Education (ROSE) Project began in North Carolina. This community-based education project targeted Caucasian, African-American, and Native American women over 40 years old. In this study Electra D. Paskett, Ph.D., Director of Center for Population Health and Health Disparities at the Ohio State University Comprehensive Cancer Center, and her colleagues characterized and compared the baseline knowledge, beliefs, and behaviors about breast cancer screening among 897 women enrolled in this project.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
