sciencehabit writes: If you've ever wondered what a virus sounds like, or what noise a bacterium makes when it moves between hosts, you may soon get your chance to find out. Scientists have created the world's tiniest ear. The "nano-ear," a microscopic particle of gold trapped by a laser beam, can detect sound a million times fainter than the threshold for human hearing. Researchers suggest the work could open up a whole new field of "acoustic microscopy," in which organisms are studied using the sound they emit.
The ideal voice for radio may be defined as showing no substance, no sex,
no owner, and a message of importance for every housewife.
