Limits on marketing cigarettes may be undercut by user-generated YouTube videos. A study of adolescents finds it's possible to counteract such pro-tobacco videos with a corrective message.

APPC postdoctoral fellows presented their research overseas, speaking on GMOs and risk perceptions at a Society for Risk Analysis forum in Italy and on publication bias at a talk in Germany.

Researchers from the Annenberg Public Policy Center presented work on public attitudes toward science at the American Association for the Advancement of Science meeting in Boston.

A study finds that early drug use strongly predicts substance abuse only if it’s followed by continuing drug use. Early experimentation with alcohol or marijuana isn't necessarily a risk factor for addiction.

Science curiosity appears to counteract people’s tendency to seek out only information that supports their political biases, according to a new study finding that people who are science-curious are more willing to grapple with surprising information.

The amount of gun violence in top-grossing PG-13 movies has continued to exceed the gun violence in the biggest box-office R-rated films, according to an APPC analysis published in Pediatrics.

In 2014, 35,000 walruses crowded ashore on an Alaskan beach instead of resting on ice floes. In a newly published case study, researchers studied TV news coverage of the walrus "haul-out" and people's selective exposure to it.
