What causes bad breath? Why are dirt roads almost always scarred by kidney-jarring corrugations? No question is too daunting for Karl Kruszelnicki, who tackles the serious and the silly in science as a radio show host on the Australian Broadcasting Corp. A former physicist, engineer, and rock roadie, Dr. Karl has made important contributions to human knowledge, winning an Ig Nobel prize, the mock science award, for his study of belly button fluff. You can listen to his hourlong call-in program online Thursdays at 11 a.m. Sydney time, which in winter is 7 p.m. Wednesday in the Eastern United States. Or check out the archive of 5-minute shows and transcripts. There you'll learn that bad breath is caused mainly by bacteria festering at the back of the tongue.
