"Because movie smoking is linked to adolescent smoking, it was important to us to clearly and quantitatively understand how and when cigarette use is depicted on screen," says James Sargent, a pediatrician and professor at Dartmouth Medical School and the Director of Cancer Control at the Norris Cotton Cancer Center at Dartmouth-Hitchcock Medical Center.
Sargent and his colleagues studied the 100 highest grossing movies each year from 1996-2004, identifying that although smoking on screen has decreased over time, it was still depicted in 75 percent of youth-rated films in 2004, including G-, PG- and PG-13-rated movies. The images of smoking in these movies have a much greater potential to reach youth audiences, because they are seen by three times as many youths than R-rated movies. The study also revealed that, overall, the proportion of movies containing cigarette use or imagery declined from 96 percent in 1996 to 77 percent in 2004.
"While we do see a downward trend in movie smoking, which is encouraging from a public health perspective, we need to remember that youths continue to see smoking in most of the movies they see," says Sargent.
To further decrease the access that adolescents have to smoking scenes and depictions, the authors recommend an R rating for all movies with smoking. The authors say that an R-rating for smoking could reduce potential exposure of youth to movie smoking in new releases by about 50 percent, resulting in a substantial reduction in exposure over time. The American Legacy Foundation report was co-authored by Sargent, Keilah Worth and Susanne Tanski, all at Dartmouth.
Sargent and his colleagues study adolescent behavior and how it's linked to exposure to movies. They have published numerous papers and articles describing how adolescents are exposed to thousands of depictions of smoking by movie stars, and these images influence their attitudes and behaviors regarding smoking.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
