Microbe buffs can get an earful of information from their iPods every day, thanks to the American Society for Microbiology. The society has begun podcasting its MicrobeWorld Radio, a 90-second daily program of microbiology news. Pod people can automatically download new episodes as soon as they go online, then listen to the files on the computer or a digital audio player. Recent MicrobeWorld Radio shows have explored subjects such as methane on Mars, a possible indicator of life, and antimicrobial foods such as garlic and dried plum extract.
