Fox Chase Cancer Center researchers and their colleagues have developed a mouse model of the most prevalent and deadly form of human ovarian cancer -- epithelial ovarian cancer. The mouse model provides a better opportunity to study the cause of ovarian cancer, examine the genes involved and test preventive, diagnostic and treatment approaches that could be applied to human ovarian cancer.
"These transgenic mice offer us a valuable scientific tool that never before has been available to ovarian cancer researchers," explained Fox Chase Cancer Centers Denise C. Connolly, Ph.D., corresponding author of the study, which appears in the March 15, 2003, issue of Cancer Research, a journal of the American Association for Cancer Research.
The mice engineered by Connolly and her colleagues develop epithelial ovarian cancer in both ovaries. This cancer arises in the surface, or epithelial, cells of the ovaries. The mouse model was made by introducing a genetically engineered DNA fragment into fertilized mouse eggs prior to their embryonic development. The fragment is a combination of a gene specific promoter and a potent oncogene. The oncogene, Simian virus 40 T antigen, triggers cancer development. The promoter is derived from a gene (Mullerian inhibitory substance type II receptor) that signals the expression of a specific protein found in cells covering the ovaries.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
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...
