These findings are specific to the Minnesota Adolescent Community Cohort study, a longitudinal telephone survey of youth less than 18 years old. The probability of an adolescent as young as 12 years of age buying cigarettes from a commercial source in the past month decreased significantly from 36% at baseline to 22% after three years.
In sharp contrast, the probability of their obtaining cigarettes from a social source in the previous month during the same time period increased significantly from 54% to 76%. “Although the use of social sources for cigarettes may increase when the commercial supply of cigarettes is restricted, the total amount of youth smoking seems to be reduced by increased commercial restrictions” comments Dr. Widome, the corresponding author.
These results are important because they indicate a decreasing access to commercial sources of cigarettes. It is well established that, apart from illegally buying their tobacco from commercial sources, underage smokers also obtain their tobacco from social sources like friends, relatives, older adolescents, and adults. For 14 to 18 year old minors in the US, the usual sources of cigarettes are a store (23.5%) or vending machine (1.1%); giving someone else money to buy them (29.9%); borrowing them from someone else (30.4%); stealing them (4.4%); or getting them in some other way (10.7%), which includes via the internet.
The good news in Widome et al.’s findings is that adolescents who obtained cigarettes from social sources were less likely to become heavy smokers compared to youth who bought their cigarettes from commercial sources.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
