TV advertising shown to be most effective
Most smokers want to quit, but even among those who try, less than 5% manage to stop smoking for more than three months. There is a major ongoing effort to encourage quitting, the National Action Plan for Tobacco Cessation. This comprehensive plan has six main initiatives, only one of which, a national telephone quit line, has been implemented to date. To evaluate the effectiveness of various strategies, researchers identified 787 people who had quit smoking in the past two years and asked them what had worked for them.
The results, reported in the March issue of the American Journal of Preventive Medicine, evaluated the effect of televised ad campaigns promoting quitting and seven conventional types of cessation help; nicotine replacement therapy (NRT), prescribed medications, professional help or advice, self-help materials, cessation programs, telephone quit line, or web-based cessation sites. The impact of a particular quitting aid is measured by multiplying the efficacy rate by its participation rate or penetration into the population. For example, Method A might not be as effective as Method B for individual smokers, but if Method A reaches 90% of all smokers and Method B reaches only 5%, Method A might be the better choice as part of a national program.

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...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
