Podcast: Ask the Naked ScientistsPublished On: Thu Sep 30 2010

And why are planets spherical? We tackle all of these questions this week, as well as finding out that researchers have created an artificial nose even more sensitive than a dog's. Plus we'll discover why onions make your eyes water... Like this podcast? Please help us by supporting the Naked Scientists
