Women who used the once-a-week birth control patch, ORTHO EVRA® (norelgestromin/ethinyl estradiol transdermal system), were more likely to use their medication as directed than women who took a birth control pill, according to a study published in the current issue of Contraception.
"It’s not always easy, but it is very important for women using any birth control pill to take it at the same time every day to prevent unplanned pregnancy," said Vanessa Cullins, M.D. FACOG. "What’s exciting is that this study shows that the birth control patch is convenient and simple to use, and may be a better birth control option for women."
Oral birth control pills must be taken consistently and correctly to be effective, however an estimated 15 percent of oral birth control users say it is difficult to do so with the Pill. Inconsistent or incorrect use, i.e., missing one or more pills per cycle, can increase the risk of unplanned pregnancy and lead to abnormal bleeding, which is the leading cause of unscheduled physician visits. In the study, previously published Phase III data were analyzed to further explore compliance differences between ORTHO EVRA and an oral contraceptive. These results showed that the percentage of cycles with "perfect dosing," a measure of correct dosing of a birth control method, was significantly higher with the patch (88.7 percent) than oral contraceptives (79.2 percent).

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.

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...
