If you could press your ear to a ladybird’s chest, what would you hear? Not the steady thump thump of a human heart, but something quite different. Discovery News reports on work carried out by Igor Sokolov and his team at Clarkson University, who used an atomic force microscope to listen to the faint sounds emanating from inside living insects.
The researchers used this atomic stethoscope to record the internal sounds of other insects including a fly and a mosquito, which you can listen to here.
The work is published in Applied Physics Letters.
