Breathing easy: When it comes to oxygen, a bug's life is full of it

t control in agriculture.

Jake Socha, Argonne National Laboratory, Chicago, and the University of Chicago will discuss “Control of internal convection in beetles using active tracheal compression.?Socha, a biophysicist, is best known to the public for his work on “flying?snakes. He has used synchrotron x-rays to view working tracheal tubes and air sacs in living insects that give further clues to how the system works. Insects employ autoventilation (using wings or legs to pump air through the body), abdominal pumping (using the muscles in the abdomen to pump air), and tracheal compression (getting oxygen to the head and thorax).
