9. Ghost Heart 

The scientist keeps
a mouse heart in a glass
bulb, a wet white blob,
like cotton soaked in alcohol. 

She washes it with soap
to break the old cells down,
and makes a scaffold for new
ones to cleave to.  It starts
to twitch; it starts to act
like it's a heart. 

In the lab, someone in a white coat
shouts, "Doris, it's healing."
