You may recall a prior blog in which I talked about the wonders of whale poo and a substance called ambergris that can be either defecated or regurgitated by whales and is used to make expensive perfumes. Well, my favorite comic strip, Piled Higher and Deeper (i.e. PhD Comics), posted a 2-minute thesis presented by Baillie Redfern from the University of British Columbia on how whale barf is used in perfumes and how her research is attempting to re-create the wonders of ambergris in the lab. These 2-minute thesis presentations are great. Keep it up PhD Comics!
