"I look for aliens" is how high-flying young astrobiologist Lewis Dartnell describes his work, and we hear the wheres and hows of that search in this week's episode. During the fascinating chat Lewis explains how aliens might resemble anything from bacteria to "sky whales", Roo has a question about methane, and Leila jumps at the chance to defend Spock.
Elsewhere this week, a generous listener supplies us with some very exotic snackfood from China, and Dave joins us to review it in possibly most gruesome installment of "Around the World in 80 snacks" so far. And don't forget that all episodes of the podcast are available on audio cassette, and our exclusive Audible offer still stands - so get your audio book here.
