Nova ScienceNow is a newsmagazine version of the long running and venerable PBS science program Nova. Premiering on January 25, 2005, the series was originally hosted by Robert Krulwich, who described it as an experiment in coverage of "breaking science, science that's right out of the lab, science that sometimes bumps up against politics, art, culture". At the beginning of season two, Neil deGrasse Tyson replaced Krulwich as the show's host. David Pogue is scheduled to host the upcoming season six. Unlike the parent program Nova, Nova ScienceNow has a whimsical production style. It is not... unusual for the show to explain topics as arcane as RNA interference using cartoons, or a solution to a two-thousand-year-old math problem related in song. Whereas Nova covered a single seamless subject in each hour-long episode, NOVA scienceNOW covers several related, but distinct, story segments during the course of each program. The show also features 30-60 second short segments between each story segment, taking the place and pace of commercials in an otherwise uninterrupted program flow.
