According to a new study, when it comes to smoking, adolescents may be emulating the movie stars they see on the big screen. Writing in the December 15 issue of the British Medical Journal, researchers at Dartmouth College report that they have found a link between tobacco use in movies and smoking amongst young people.
James D. Sargent and colleagues questioned 4,919 New England middle school students between the ages of nine and 15 about their smoking habits and movies they had seen. "For better or worse, adolescents watch a lot of movies," Sargent explains. "So many that they might see more smoking in films than in the real world."
The researchers counted cigarette smoking activity in 601 popular films released in the United States between 1988 and 1999. The questionnaires asked students to identify movies they watched from a list of 50 randomly selected titles, ranging from The Addams Family to The X-Files. The team then compared the students exposure to smoking in films to their personal smoking history. Students with the highest exposure to movie smoking, the study found, were more than two and a half times as likely to take up smoking compared to those with the least exposure when other influential factors such as peer smoking, smoking by parents, school performance and rebelliousness were considered. "With this survey, weve shown that what teens see in the movies is statistically linked with what they do," Sargent notes.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
