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 look exclusively at bulimia. Earlier this year, another linkage scan found evidence of genes for the eating disorder anorexia nervosa on chromosome 1.
This study, led by Walter H. Kaye, M.D., a professor of psychiatry at the University of Pittsburgh Medical Centers Western Psychiatric Institute and Clinic (WPIC), and authored by Cynthia M. Bulik, Ph.D., a professor in VCUs Department of Psychiatry and a researcher at the Virginia Institute for Psychiatric and Behavioral Genetics in Richmond, VA, appears today in the online edition of the American Journal of Human Genetics. It will be published in the Jan. 1, 2003 print edition.

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...
