On this episode of PNM, reporter Matthew Zmudka had two completely different segments:
-A reflection on his experience taking an online course entitled “Changing Weather and Climate in the Great Lakes”, with an interview of course coordinator Margaret Mooney.

-An interview with UW-Madison researcher Graham Erwin, discussing the process of DNA transcription, how that is controlled through an organism, and what scientists are doing to harness that control for medicinal purposes.
