The study was conducted at the University of Southern California (USC) and appears in the journal Child Development.
Researchers looked at 1,260 ethnically diverse, urban, middle-class sixth through eighth graders. They asked the students about their own smoking behavior, and they asked them to name friends at school as well as the organized sports they took part in at school. Then, using a social network method they developed, they examined how participation in sports with teammates who smoked affected adolescents' smoking behavior.
They found that youths were more likely to smoke as they were increasingly exposed to teammates who smoked, and that this tendency may be stronger among girls than boys. But they also found that youths who took part in a greater number of sports were less likely to smoke than those who participated in fewer.
"This result suggests that peers on athletic teams influence the smoking behavior of others even though there might be a protective effect overall of increased participation in athletics on smoking," according to Kayo Fujimoto, assistant professor of health promotion and behavioral sciences at the University of Texas Health Science Center at Houston, who led the study when she was at USC.
The study has implications for programs aimed at preventing teens from smoking. "Current guidelines recommend the use of peer leaders selected within the class to implement such programs," Fujimoto points out. "The findings of this study suggest that peer-led interactive programs should be expanded to include sports teams as well."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
