Postmenopausal women are weaker, as measured by grip and pinch tests, than women who have not entered menopause, according to a study published in the American Journal of Epidemiology. However, the researchers found that physical activity protected women from losing strength as they progress through menopause.
Researchers at Rush University Medical Center and the University of Chicago Hospitals followed a racially mixed group of 563 Chicago-area women for five years. Strength tests determined how firmly they could grip and pinch. The results of these tests were assessed against the womens age, state of menopause, ethnicity, income and use of hormone replacement therapy.
Women who participated in the study were tested for grip strength with a handgrip dynamometer and a pinch gauge was used to measure strength over the course of the study. Statistical models were developed to assess whether menopausal status was associated with grip and pinch strength. Other variables, such as race and body mass index, were controlled for.

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...
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.
