Smoking not more common in movies than US population
New research shows that lower-class, nonsuccessful "bad guys" smoke more often in movies than wealthy movie heroes, a finding that contradicts previous research examining smoking in the movies. A study published in the August issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians, is the first objective, prospective analysis to quantify the prevalence of smoking in contemporary American movies and show that smoking is not more common in movies than in the general US population.
"Most investigators have concluded that smoking is portrayed as glamorous and positive, but our study shows that the exact opposite is true," said the studys lead author, Karan Omidvari, MD, FCCP, Heart and Vascular Institute, St. Michaels Medical Center, Newark, NJ. "Additionally, different studies in the past have subjectively concluded that movies are attempting to influence different groups of minorities to smoke. We have contradicted these findings as well."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
