Nearly 20 percent of smokers using an over-the-counter nicotine patch in a new study were able to quit smoking entirely after six weeks, compared to only 7 percent of smokers using a dummy patch. Each group reported only mild side effects from patch use, like rashes or insomnia.
None of the smokers received any direct instruction on how to use the patch or got behavioral counseling to help them quit smoking, which suggests that nicotine patches used in an over-the-counter manner can be safe and effective, say the study authors. The study was supported by GlaxoSmithKline Consumer Healthcare, which markets the NicoDerm CQ patch.
"Most smokers still try to quit without the benefit of treatment; their odds could be improved by the use of the nicotine patch," says lead author Saul Shiffman, Ph.D., of Pinney Associates and the University of Pittsburgh and colleagues. "Our study suggests that over-the-counter nicotine patches can nearly triple a smokers chances of quitting."

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
