Cyborg rats will save you

We know this sounds crazy, but pretty soon rats with probes wired into their brains will be deployed to earthquake and other disaster areas to help try and help locate survivors. The rats are trained to recognize the smell of humans
(they do this by using another implant to directly stimulate the "reward center" of their brain—where do we sign up for one?) and when that human-smell recognizing part of the brain is triggered the signal is then relayed to a little radio trasmitter, which beams the info back to rescue workers. The rats can also be trained (and wired) to look for explosives. Sounds a little bit like someone's been rereading The Secret of Nimh to us.
