A team of researchers at Virginia Commonwealth University (VCU) and the University of Pittsburgh Medical Center have linked an area of chromosome 10p to families with a history of bulimia nervosa, providing strong evidence that genes play a determining role in who is susceptible to developing the eating disorder.

The finding, gleaned from blood studies of 316 patients with bulimia and their family members, is the result of the first multinational collaborative genome-wide linkage scan to lo

Rush is first site in the Chicago area to obtain the stereotaxis technology and one of only two in the world with an emphasis on neurosurgical applications

Neurosurgeons at Rush-Presbyterian-St. Luke’s Medical Center have become the first in the Chicago area to use a radically new, magnetically controlled system to enter the brain and its vascular system to treat a variety of diseases without surgically opening up the skull and brain.

“Magnet-guided neurosurgery allows

Key step in process of developing targeted therapeutics to combat epilepsy

Scientists from Toronto’s Princess Margaret Hospital are able to depict for the first time how an important molecule called IP3 and its receptor interact to control calcium levels in cells, a process that is vital to normal brain function.

The study is published in this week’s edition of the international scientific journal Nature, and is a collaboration between scientists at Princess Margar

A new clinical trial has shown that reducing the interval between successive doses of a commonly used chemotherapy regimen improves survival in women whose breast cancer has spread to the lymph nodes. While previous research has evaluated the use of various forms of “dose dense” chemotherapy, this is the first major controlled study to show a clear survival benefit for women with node-positive breast cancer. The study was conducted by Cancer and Leukemia Group B (CALGB) for the Breast Cancer Intergro

Through precise control of the etching process, an inventor in Oxford University’s Photofabrication Unit has made the reliable production of High Resolution Printed Circuit Boards (PCBs) with conductors down to 10 µm wide more of a cost-effective reality.

With increasing demands for greater miniaturisation and the use of flexible circuitry, the need for improved fabrication methods for high resolution printed circuit boards is becoming more important. PCBs currently include conductors with

Biodiversity worldwide may be decreasing, but at smaller scales it is increasing or at least changing in composition, suggesting the need for a dramatic shift in the current focus of ecological research. These changes may undermine the functioning of local ecosystems, according to an article in December’s American Naturalist.
