In Mark Sussman's lab at San Diego State University, a machine showing what looks like a sonogram that obstetricians use to image unborn babies in the womb instead shows the tiny heart of a mouse.
What is visible is actually a cross section of the heart that looks like a doughnut. The hollow center is the heart's chamber, the circle of tissue around it the walls of the animal's heart.

The heart is not in good shape. Lab technicians had tied the ascending aorta in the animal, akin to bending a kink in a hose, so that pressure built inside the heart.
The heart's response?
