According to the Telegraph:


A British research scientist is training 170 rodents which she describes as nimble, agile and perfect for use in disaster zones.


Rats are being trained to be sent into earthquake debris wearing tiny backpacks so that rescue teams can talk to survivors.

Seven rats have been trained so far, taking two weeks to get them up to speed.

Prototype backpacks containing a microphone are being used at the moment, with rats being sent into mock debris.

Specialist backpacks containing microphones and video gear as well as location trackers will be created to allow rescue teams to communicate with survivors during real earthquakes.
