Although most humans probably do not lament the disappearance of dog-sized insects, a handful of scientists do. These scientists obviously don't watch the same movies we do. Recently, a group of researchers from Argonne National Laboratory's Advanced Photon Source along with some other researchers from less badass sounding institutions used advanced x-ray equipment to try to determine why giant insects don't roam the earth devouring amorous teenage couples today. X-ray imaging of beetles helps confirm that tracheal system design may limit size in insects.The answer lies in their primitive…
