Eavesdropping on Microbes

In a world of ever shrinking gadgetry, I think that there must be a limit. That we will read a point where we can't get any smaller. For eavesdropping, however, the size has just shrunk by an order of magnitude or more. Scientists have devised a way to trap the vibrations generated by small molecules and organisms and amplify them into sounds we can hear, Check it out at BBC News, "Tiny ear listens to hidden worlds."
