Panoramic dental x-rays can be used to help identify postmenopausal women with low skeletal bone mineral density (BMD), meaning that screening for spinal osteoporosis could begin in the dentists office a new study shows.
The study included 316 postmenopausal women who had no symptoms of osteoporosis. The women were divided into two groups: 159 had no history of hysterectomy, oophorectomy or estrogen use, the remaining 157 had one or more of these histories. All had panoramic dental x-rays, and the cortical shape and width of the jaw were estimated on the x-rays. "Women with eroded cortical shape need to be referred for further BMD testing," said Akira Taguchi, DDS, PhD, department of oral and maxillofacial radiology at Hiroshima University Hospital in Japan.
Currently, questionnaires are widely used as the first step in determining which women need to have further BMD testing. This study found that dental x-rays were just as sensitive as questionnaires in identifying those women. Dental x-rays, looking at cortical shape, were 87% sensitive in identifying women with spinal osteoporosis in the group with no history of hysterectomy, oophorectomy or estrogen use and 80% sensitive for the other group. The questionnaire was found to have an 87% sensitivity rate for the women with no history and 72% for those with the history of hysterectomy, oophorectomy or estrogen use, Dr. Taguchi said.

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...
