I heard about this research this morning - it builds upon that conducted by Australia's very own Dr. Karl who won an IgNoble for his research on belly button lint!

Dr Karl Kruszelnicki has made science fun for a whole generation of Australians. A survey at Sydney University, where he holds the Julius Sumner Miller Fellowship, found that one in seven students had chosen their career specifically because of him. Using radio, TV, newspapers, books and the Internet, he's addressed every conceivable question about the universe, from the profound to the deeply inane. Please welcome a man with an unfailingly curious mind and a licence to use it.
