You Can’t Run From Death

(A student is giving a presentation on analyzing some microscope movies of cells. Prof #1 is well-known for being a keen marathon runner.)

Student: “To determine cell death, we have three inputs: the distance trace, the fluorescence trace, and the coefficient of variance.”

Prof #1: “I don’t understand how the distance trace shows cell death.”

Prof #2: “When you’re dead, you stop running.”
