The Naked Scientists is a one-hour audience-interactive science radio talk show broadcast live by the BBC in the East of England, nationally by BBC Radio 5 Live and internationally as a podcast. The programme was created and is edited by Cambridge University Pathology Department consultant virologist Dr Chris Smith. He hosts the show with other scientists. The present Naked Scientists line up includes producers Ben Valsler and Meera Senthilingam, scientist David Ansell, marine biologist Helen Scales and blogger and harpist Kat Arney. The group appointed the first official Naked Scientists PhD student, Diana O'Carroll, who is examining the educational impacts of science broadcasting and new media. O'Carroll also presents a Naked Scientists spin-off podcast, Naked Archaeology, which launched in 2008. A second spin-off, Naked Astronomy, a Valsler production featuring Cambridge University-based space scientists and astronomers, has been podcast since December 2009, and a combined video and audio programme, Naked Engineering, which is produced by Ansell and Senthilingam and supported by the Royal Academy of Engineering, launched in September 2010. For Christmas 2010 the group also showcased a new video podcast strand, the Naked Science Scrapbook.
