If you cover your ears with your hands, you can listen to your heartbeat and some of the other internal buzz and hum that goes on inside of your body. These are familiar sounds to all of us. For the first time, however, scientists have just recorded sounds emanating from inside living insects, such as flies, mosquitoes and ladybugs.

Igor Sokolov and his team at Clarkson University managed this feat using atomic force microscopy, a very sensitive tool that’s popular now in nanotechnology. It records sub-nano oscillations of very faint noises, less than the amplitude size of a single atom and at incredibly high frequencies—up to 1,000 hertz or cycles per second.

Similar to using a stethoscope, the researchers placed a probe for this device on top of each bug to capture the recordings.
