When did I get beamed to opposite planet?

After five weeks of learning to make nice, stable sample slides that will last for hours of data-taking, on Monday I suddenly had a change of assignment.  It is now my job to see how much abuse aforementioned slides can take before everything on them falls apart, so I have been trying my level best to destroy the fragile molecules tethered there with all the nasty acids and denaturants I can throw at them.  Needless to say, my *cough* fragile *cough* nucleic acids have drifted through it completely unscathed.
