Flaxseed-rich diet blocks prostate cancer growth and development in mice

A diet rich in flaxseed seems to reduce the size, aggressiveness and severity of tumors in mice that have been genetically engineered to develop prostate cancer, according to new research from Duke University Medical Center. And in 3 percent of the mice, the flaxseed diet kept them from getting the disease at all.

“We are cautiously optimistic about these findings,” said Wendy Demark-Wahnefried, Ph.D., associate professor, division of urology and senior author of the study that appears in t

Engineering researchers demystify fatigue failure in polysilicon used in MEMS devices

The success of many advanced technologies that use devices such as sensors and actuators, including gyroscopes and optical devices, depends on microscopic components called microelectromechanical systems (MEMS) devices made of polycrystalline silicon (polysilicon). Researchers at Case Western Reserve University report in the November 8 issue of Science that miniature micron-sized polysilicon laboratory specimens subjected to cyclic tension/compression loading undergo fatigue, and could ultimately fa

NIST micro-positioner may help send messages from the stars

Phoning home from 93 billion miles away–only E.T. and other science fiction characters can do that. But with the help of National Institute of Standards and Technology (NIST) know-how, reality soon may catch up with imagination.

Conceptual designs for a “realistic interstellar explorer,” or RISE — a highly autonomous craft that would travel far beyond this solar system to collect scientific data — call for a laser-based communications link to Earth that relies in part on a recent NIST i

NIST solving a mystery among electrons

When it comes to sleuthing in science, few are better than the intrepid investigators at the National Institute of Standards and Technology (NIST). For example, take the “Case of the Stray Electrons.”

NIST researchers have created nanoscale devices that manipulate electrons in order to count them one at a time. Such counting is critical to the development of new fundamental electrical standards. When two electrons are bound in pairs (called Cooper pairs) in a superconductor, they can be man

Greening Africa`s Desert Margins

Global Environment Facility Funds New UNEP Poverty-Busting Project Promising New Hope to People and Wildlife

A pioneering new project to heal dying and degraded lands fringing Africa`s mighty deserts was launched today by the United Nations Environment Programme (UNEP) and the Consultative Group on International Agricultural Research (CGIAR).

The project, marking a new phase of the five year-old Desert Margins Programme, has numerous aims including conserving the rich and uni

Flip chips are altering the face of electronic packaging

Technical Insights’ Sensor Technology Alert

Flip chip packaging delivers enhanced electrical performance, saves space, and provides high conduction speed, making it an ideal technology for use in handheld devices and medical electronics, among other applications.

“As integrated circuit fabrication advances rapidly and the market for faster, smaller, yet less expensive electronic products accelerates, flip chip packaging comes into play,” says Technical Insights Research Ana
