Study Examines Placement of Tobacco and Alcohol Brands in Movies Rated for Youth Audiences

An analysis of top box-office movies released in the United States indicated tobacco brand producer placements in movies have declined since implementation of the Master Settlement Agreement (MSA), but alcohol placements, which are subject only to industry self-regulation, have increased in movies rated acceptable for youth audiences, according to a study published Online First by JAMA Pediatrics, a JAMA Network publication.

GATA-3 Is Important for the Regulation and Maintenance of the Immune System

The protein GATA-3 plays an important role in mammalian immune response, but its overall function in cell development and cancer formation is not well understood. In an effort to further define the importance of GATA-3, researchers at the University of North Carolina have traced how the protein performs important functions in CD8+T-cell type of the immune system.

Understanding the Past and Predicting the Future by Looking Across Space and Time

In a new paper published this week (May 20) in the Proceedings of the National Academy of Sciences, researchers from the University of Wisconsin–Madison and elsewhere validate a fundamental assumption at the very heart of a popular way to predict relationships between complex variables.

Newly Understood Circuits Add Finesse to Nerve Signals

An unusual kind of circuit fine-tunes the brain’s control over movement and incoming sensory information, and without relying on conventional nerve pathways. The work may provide insight into the design of drugs for autism and movement disorders.
