The authors of a new study published in Human Communication Research say that the media is losing some its ability to sway viewers on important social issues. Specifically, the study shows that the 'OC', a crummy drama series about teens and their turbulent lives in southern California, may be more effective in persuading young women to use birth control than a news-format program on the same issue.

The results show the power that narratives like TV shows can have in influencing people, said Emily Moyer-Gusé, co-author of the study and assistant professor of communication at Ohio State University.

A new commentary just published in the Proceedings of the National Academy of Sciences claims that more evidence is mounting that birds did not evolve from ground-dwelling theropod dinosaurs and challenging decades of accepted theories about the evolution of flight.

The weight of the evidence is now suggesting that not only did birds not descend from dinosaurs, but that some species now believed to be dinosaurs may have descended from birds, according John Ruben, a professor of zoology at Oregon State University who authored the PNAS commentary.
